Contact us to discuss lens designs using any of these moldable glasses.
Molded Glass Lens Arrays
By utilizing LightPath’s molded lens technology it is now possible to manufacture lens arrays
with high precision. Unlike etched lens arrays, where there is a great deal of non-uniformity
from array to array, molding will consistently produce the same structure and performance
from prototype to large production builds. Consistent focal lengths and form ease the
manufacturing requirement for the end user. The molding technology also allows optical
designs that require greater sag (lens thickness) such as high numerical aperture collimators
for laser diode arrays. Lens arrays can be produced for direct coupling (finite conjugative) or
collimating applications. Pitch tolerances are typically less than one micron and lenses can also
be placed with varying pitches across the array.
Tx™ Asphere Wafer-Based Molded Optics
Designed and manufactured for today’s high performance transmitters, Tx™ Aspheric lenses utilize LightPath’s proprietary wafer-scale glass
manufacturing techniques, delivering performance, size and price. By molding an entire wafer of lenses at one time and then dicing them
individually, production cost is significantly reduced over single lens molding. The dicing operation results in a square form factor lens that can
make mounting easier. All lenses are 100% inspected, tested, and AR coated.

Spherical vs Aspherical Lens Systems
Spherical System
Aspheric Optics
For today’s sophisticated and compact laser systems, aspheres are
the most powerful lenses for managing laser light. In these systems,
spherical aberration is the most prevalent performance detractor. It
arises from the use of spherical surfaces and artificially limits focusing
and collimating accuracy.
Aspheric Lens
Although it has been known for centuries that spherical geometry
is not optimal for refracting light, the expense of fabricating nonspherical (aspheric) surfaces has inhibited their use. With the
breakthrough of LightPath’s glass molding technology, this optimal
lens geometry has become a reality.
Working Center
Distance Thickness
Molded lenses are used in a variety of photonics products: barcode
scanners, laser diode to fiber couplings, optical data storage, and
medical lasers, to name a few. In many of these applications, the
material of choice is optical glass because of its durability and
performance stability over a wide environmental range. High power
transmittance is also an added advantage.

The benefits of glass molding technology become apparent when traditional methods of grinding and polishing become cost-prohibitive. The
direct molding process eliminates the need for any grinding or polishing, offering aspheric lenses at practical prices for system designers. Molding
is the most consistent and economical way to produce aspheres in large volumes.
Small and lightweight, our aspheres collimate or focus light as a single element. This means less complex systems, fewer alignment requirements,
less re-work and shorter assembly time. Our aspheres are molded; therefore the lenses have excellent piece-to-piece uniformity. They are made
of glass, which is the most durable optical material available, capable of withstanding repeated cleaning and performing at specification despite
extreme temperature and moisture variations.
Guaranteed Performance
LightPath’s aspheric lenses are inspected and optically tested to ensure complete
customer satisfaction. Visual cosmetic inspection is preformed on 100% of all
lenses per MIL-PRF-13830B with a scratch/dig spec of 40/20. Other inspection
criteria including 80/40 and 20/10 can be provided upon request.

Optical performance is guaranteed by test methods utilizing 632.8 mm interferometer measuring transmitted RMS wavefront error listed in the
individual lens specification. LightPath can also perform customized optical tests in order to screen for specific application criteria.

Geltech Aspheric Lenses
Optical Performance
Lens Holders
The primary optical specification is the root-mean-squared
transmitted wavefront error (RMS WFE). It is measured on a phase
shift interferometer at the wavelength of 632.8 nm. Most of our
lenses are guaranteed to be diffraction limited, which means the
RMS WFE < 0.070 λ at the design wavelength.
Several of our catalog lenses are available pre-mounted in metal
holders. Using our unique Mold-In-Place (MIP) technology, we can
actually mold the lens directly inside of a steel holder, eliminating the
need for adhesives in your package. We can epoxy our lenses into
Stainless Steel or Kovar mounts so you can weld them directly into
your system.
Numerical Aperture
Aspheric Optics
Our molded aspheric lenses are available with numerical apertures
ranging from 0.15 up to 0.83. Lower NAs are best when a large
depth of focus is important or when you need nearly circular beams.
Examples of applications that would use a low numerical aperture
are bar code scanners, surveying instruments, and small weapons
sights. High numerical aperture lenses are important when you
need to focus light down to a small spot size or when you need the
maximum light capture from a diode laser. High numerical aperture
applications include data storage and industrial printing.
Shapes and Sizes
Custom Aspheres
LightPath aspheric lenses are typically plano-convex or bi-convex,
with diameters as large as 25 mm or as small as 0.250 mm. LightPath
has the capability to dice the lenses to specified shapes for easier
mounting.
Our catalog details 53 standard types of available aspheric lenses. If
you do not see a lens that fits your particular application, we would
be happy to design one for you. Our sales and engineering
teams work closely together to assist you in design, prototyping, and
production of custom glass aspheric lenses. LightPath offers custom
lens solutions for high volume manufacturing at prices equal to those
of standard off-the-shelf lenses. We pride ourselves on being the
fastest custom lens designers in the industry.
When determining specifications for custom aspheric lenses, the
following parameters are typically used to specify lens performance.
A LightPath product expert would be happy to discuss the following
list of parameters with you to determine the appropriate lens for
your application.

Aspheric Optics
D-ZLAF52LA → 355xxx Series of Lenses
This glass has a higher index of refraction than ECO-550 and is best suited for those applications that require a higher index and
need to maintain RoHS compliance.
D-ZK3 → 354xxx Series of Lenses
This glass is best suited for those applications that require a low cost glass for higher volume manufacturing.
ECO-550 → 352xxx Series of Lenses
New European (RoHS) and Japanese environmental regulations have restricted the use of lead and other hazardous substances in optical
components. ECO-550 is an environmentally friendly alternative to conventional moldable glasses. It has similar optical properties to C-0550, but
does not contain hazardous materials.
C-0550 → 350xxx Series of Lenses
Corning ® developed a special glass to allow production of highly sophisticated aspheric lenses that are cost effective. The code
for this glass is C- 0550, and its low dispersion (νd = 50.40) is key for many applications. In durability, it is equivalent to Corning ®
BCD C2060 or Schott ® SK16. Due to limited availability, this glass should only be used for special projects that require its unique
proper ties.
PBH71 → 370xxx Series of Lenses
For aspheric lenses that require a glass with a higher index of refraction, LightPath also offers lenses made from Ohara® PBH71 glass. Its high index
(nd = 1.92286) allows designers to minimize aberrations in lenses with high numerical apertures. It has the added benefit of a lower coefficient
of thermal expansion.

Choosing
theAspheric
Right Aspheric
For Diode Collimation
For example, if the half max NA for a laser is used with the above
formula, you will get the half max beam diameter. There is no simple
way to convert from a half max number or a 1/e² beam diameter
to a full beam diameter for a specific source because it depends on
the intensity profile of the source itself. A reasonable approximation,
though, for most edge emitting diode lasers is to assume a Gaussian
beam profile. Using this beam profile, you can convert the beam
diameters as follows:
One of the most common uses for aspheric lenses is in the
collimation of edge emitting diode lasers. With over 35 standard
lenses in LightPath’s catalog to choose from, however, this can
sometimes be a confusing task. The guide below will clear up some
of the questions about choosing the best lens to use with a specific
laser for a particular application.
Aspheric Optics
Due to the way that the laser cavity is constructed in edge emitting
diode lasers, light is emitted in a diverging, elliptical geometry - so the
divergence is typically specified in both the x and y axes separately.
The axis with the larger divergence is called the “fast axis” and the
axis with the smaller divergence is called the “slow axis”.
1. To convert a half max beam diameter to a full beam
diameter, multiply the diameter by 2.576.
2. To convert a 1/e² beam diameter to a full beam
diameter, multiply the diameter by 1.517.
When selecting a lens to collimate the laser, first consider the
Numerical Aperture of the lens. If the application requires a high
amount of the laser light to be coupled though the system, a lens
with a high enough NA must be chosen. The NA of a lens is a
measure of the maximum amount of divergence that the lens can
capture from the laser. Ideally, a lens should be used that has an NA
higher than the NA of the laser’s fast axis. If not, the laser will “clip”
the lens causing some of the light to be wasted. To convert the laser
NA to the divergence angle (and vice-versa), use this formula:
Remember that most edge emitting diodes are elliptical, so the
beam diameter will be different in the x-axis versus the y-axis. Use
the formula above to calculate the beam diameter in both axes to
determine the shape of the collimated, elliptical beam.
For Fiber Coupling
Another common use for aspheric lenses is to couple laser light into
optical fibers. Choosing the right lens or lenses to do the coupling is
important to maintain high efficiency in the optical system. The guide
below is intended to show how best to do this while using off-theshelf components. This guide assumes that the input laser light has
already been collimated (not diverging).
NA = n · sin (φ)
In most cases, n = 1 since the NA of the laser is defined in air
Therefore, solving for the equation is simplified to:
φ = sin -¹ (NA)
When selecting a lens to focus light into a fiber, first consider what
focal length lens is needed. Let’s revisit the formula given previously:
It is important to note that φ is the half angle of the divergence cone
and is given at the marginal ray (not 1/e² or half angle half max).
Beam Diameter ≅ 2· EFL· NA
After the minimum NA necessary for the lens is determined, next
consider what beam diameter is preferred. Although ray-tracing is
necessary to precisely determine the beam diameter for a given
NA source with a particular lens, it can be approximated with the
following formula:
Solving for EFL it becomes:
Beam Diameter
EFL ≅
2· NA
Beam Diameter ≅ 2· EFL· NA
where NA is the numerical aperture of the fiber that is used for the
coupling.
where EFL is the effective focal length of the lens and NA is the
numerical aperture of the source (not the NA of the lens).
It is important to note that the EFL value that is calculated above is
the minimum EFL needed to couple the light completely into the
fiber. Longer EFL lenses can be used, but the spot size on the fiber tip
will become larger. Therefore, it is best practice to use the shortest
EFL lens possible that is larger than the minimum value specified
above.
Important Note:
Some laser manufacturers give the NA of the source in different
terms, such as half max (50% point) or 1/e ² (87% point). Whatever
type of number is entered into the formula for the NA of the source
will be the same type of number given for the beam diameter.

Aspheric Optics
Lens Code 370930
Blue Laser Collimating Lens
• Optimized for Nichia blue laser
®
• Compatible with other blue diode lasers
• Aspheric molded glass lens
• Diffraction limited performance
• Compact, single lens design
• Short wavelength provides smallest spot
Aspheric Optics
LightPath’s 352673 molded glass aspheric lens is optimized to collimate
Nichia’s® blue laser diode, and is manufactured and designed to meet
extremely stringent optical standards.
Achieving good beam quality is particularly difficult for shorter
wavelength lasers. The 352673 molded glass aspheric lenses are
designed for the specific beam divergences, peak wavelength and
window material of commercial blue diode lasers, enabling blue laser
applications to achieve excellent beam quality and performance.
Working with lasers from 400 nm to 415 nm with a design centered
at 408 nm per the laser manufacturers’ specification, this design
was optimized with a very large and forgiving clear aperture and is
also compensated for the laser manufacturers’ variation in window
thickness.
The 352673 lens utilizes LightPath’s ECO-550 glass, a lead-free
alternative to traditional moldable glasses. This glass is fully RoHS
compliant, in accordance with the new European restrictions on
hazardous substances.

Glass Aspheres for Laser Tools
• Single lens provides same performance as doublets and triplets
• Reduces system cost through simple, compact design
• Molded lenses for greater performance repeatability
In today’s manufacturing environment, laser tools are a common method
for generating guidelines and measuring distances or surface profiles. These
tools include laser levels, laser pointers, line projectors, laser scanners, and
laser trackers. LightPath’s aspheric lenses are designed for use in today’s high
performance laser tools and measurement systems.
Aspheric lenses provide a single lens solution to laser projection. These aspheric lenses provide a cost savings over spherical doublets and triplets
without sacrificing performance. Time consuming and expensive mounting and alignment of doublets and triplets can be replaced with a simple
single lens mount.
Aspheric lenses also have higher transmission than multi-lens systems due to less optical material and allow more compact packaging to be
produced.
Contact LightPath to take advantage of the power of Aspheric Optics for a simpler optical system.

Aspheric Optics
In multi-wavelength or polychromatic applications, the change in focal
length due to wavelength can compromise lens performance. For
example, if the application requires minimum spot size, as is required
in data storage or communications systems, the spot size will change
with wavelength, which can degrade system performance. In imaging
applications, an uncorrected lens results in a blurry image. A colorcorrected lens is needed to minimize these effects.
LightPath’s line of optical products for minimizing chromatic aberrations using only a single optical element. These new glass, molded asphericdiffractive lenses, also called hybrid lenses, can be used over a range of wavelengths for many applications, such as endoscopes for medical and
industrial applications, CCD cameras for imaging, as well as tunable lasers for communications products. Using LightPath’s unique precision
molded glass hybrid lenses, customers can now solve chromatic performance issues in a single glass lens, and reduce weight, volume and parts
count at the same time.
Molded In Place (MIP) Lenses
LightPath’s lenses can be molded directly into metallic holders,
allowing the lenses to be welded or soldered into the package and
eliminating the need to use epoxy. This can be an ideal solution
for high volume automated assembly or in applications where strict
outgassing requirements preclude the use of epoxy adhesives.
Anamorphic Optics
Most commercially available laser diodes project an elliptical beam
due to the diode junction having a rectangular shape. This elliptical
beam can create difficulties in many applications, such as laser to
fiber coupling. LightPath’s lens technology creates a simple solution
to circularize and collimate many of the available laser diodes. By
positioning the lens very close to the laser chip itself, these lenses
provide a small circular and collimated beam, providing a very elegant
and compact solution.

Black Diamond ™ Infrared Lenses
Mid to Long Wavelength Infrared Aspheres
• Wavelength range 1-14 m
• Aspheric lenses reduce number of lenses in a system
• Molded optics allow low cost high volume production
• Available with diffractive elements (DOE) for
enhanced performance
• Smaller focal shifts due to temperature variations
• Improved transmission at elevated temperatures
• Custom designs & catalog lenses available
LightPath is a recognized world leader in press molded aspherical
optics. Traditionally, these aspheric lenses have been limited to visible
and near-infrared wavelengths. Recent advances in optical materials
now provide a common technology path to produce mid and longwavelength infrared (MWIR & LWIR) aspheres by compression
molding. LightPath’s Black Diamond™ technology enables high
performance, cost-effective IR aspheric lenses that do not rely on
traditional diamond turning or lengthy polishing methods.
LightPath’s Black Diamond™ moldable glass has several advantages
over Germanium, which is traditionally used for aspheric IR optics.
The dn/dT and CTE of Black Diamond glass result in a smaller change
in focal length as a function of temperature. Using Black Diamond
glass enables athermalization to occur using just a single lens or with a
minimum of athermalization mechanics.
Infrared Lenses
Germanium also suffers from transmission loss as temperature
increases, especially as the temperature reaches 100°C. Germanium’s
transmission decreases by 20-30% at 100°C. Black Diamond™ aspheric
lenses can be used in environments up to 130°C, enabling a range of
applications that were not previously possible with Germanium.
LightPath’s Black Diamond™ aspheres are currently available as catalog
lenses or on a custom basis. LightPath offers custom lens solutions for
high volume manufacturing at prices equal to that of a standard off-theshelf lens. If you need a custom lens to fit your particular application,
we will be happy to design one for you. Our sales and engineering
teams work closely together to assist you in design, prototyping, and
production of custom glass aspheric lenses.
When determining specifications for custom aspheric lenses, the
following parameters are typically used to specify lens performance. A
LightPath product expert would be happy to discuss these parameters
with you to determine the appropriate lens for your application.
Utilizing aspheric optics significantly reduces the number of lenses
required for typical thermal imaging systems. Traditional Germanium
aspheres are manufactured by diamond turning, which is timeconsuming and expensive process. Since diamond turned Germanium
lenses are made one at a time, the lenses may also suffer from
variations in surface figure leading to variations in performance from
lens to lens. The Black Diamond™ molding process allows lenses to
be manufactured in high volume with highly repeatable, consistent
performance.

GRADIUM ® Lenses
• Gradient index lenses for high power laser delivery
• Aspheric performance
• Smaller focused spot size
• Single lens replacement for conventional doublets
• High performance, cost effective
• Standard designs with diameters from 5 mm to 80 mm
In high performance optical systems, spherical aberration, chromatic aberration and
astigmatism induce sweat on the brows of optical designers. These aberrations can
prevent optical systems from reaching their full potential.
Avoiding these factors in optical systems is often difficult without using multiple
lens elements. LightPath’s unique line of GRADIUM ® optics makes correcting these
aberrations with a single optical element a practical reality.
Standard Spherical Lens
Standard spherical lenses suffer from
spherical aberration, which artificially
limits the focused spot size.
GRADIUM ® lenses are made from LightPath’s proprietary axial gradient index glass.
Its unique refractive qualities can be exploited to reduce spherical aberrations –
resulting in performance similar to single-term aspheres.
GRADIUM ® lenses have been applied as simple singlets or doublets in complex multielement systems. They have been very well received for use in high-power industrial
laser systems; many of the world’s largest Nd:YAG and fiber laser manufacturers now
incorporate GRADIUM ® optics in their laser delivery systems.

GRADIUM ® Lenses
LightPath’s achromatic doublets are designed for use with collimated, polychromatic
light in the visible spectrum. The GRADIUM ® glass element is used to reduce the
spherical aberration which is a common side effect of a cemented doublet design.
GRADIUM ® Lenses
GRADIUM ® lenses take advantage of recent advances in the manufacturing of axial gradient glass. Large diameter blanks are fabricated with
index changes ( n) of up to 0.15, about 100 times that available from radial GRIN (GRadient INdex) technology. The large range in n available
provides a substantial ability to correct aberrations, especially spherical.
The process used to produce the GRADIUM ® glass turns a series of SF glass layers into a single piece of gradient material. Unlike radial GRIN
lenses, this process provides large diameter optical blanks with controlled index and dispersion profiles. Proper gradient profile selection allows
a simple spherical lens to act as an asphere.
GRADIUM ® lenses should be used wherever small spot size, high numerical aperture (NA), increased beam energy, or excellent wavefront
quality is important. A GRADIUM ® singlet does not have the limited laser damage threshold of a conventional cemented doublet, so laser power
can be increased, leading to increased production throughput.
GRADIUM ® glass offers the additional benefit of chromatic correction. The dispersion, as well as the optical index, varies in a controlled fashion
within the lens. A finished lens can be viewed as a seamless, contiguous combination of many glass types. This continuous variation results in a
transfer aberration correction not possible with homogeneous lenses.

Optical Isolator Capabilities
• Low cost RoHS
Compliant Isolators
• Epoxy free optical path available
• Flexible optical and physical design
• Design variations without major process or tooling changes
Typical Temperature and λ Dependence
Optical Isolators provide lasers with immunity from back-reflection,
thereby improving the signal to noise ratio for laser diode based
transmitters.This is especially important for high data rate transceivers
and transponders, or those devices requiring long span lengths
between transceiver pairs. All of our isolators are based on dichroic
polarizing glass and Faraday rotating crystals for highest performance.
These devices are available in a single stage, 1.5 stages, or double stages,
with multiple stages providing progressively higher isolation.
The following graphs show how isolation performance changes as a
function of temperature and wavelength for single stage, 1.5 stage,
and double stage isolators. Isolation performance increases as stages
are added to the isolator. Additional stages also reduce the sensitivity
of the isolator to changes in temperature and wavelength.
LightPath will customize isolators to be optimized for isolation
performance over a specific temperature range and wavelength.
These optimized isolators can be mass produced very quickly at
prices comparable to the standard isolators listed in this catalog.
LightPath has extensive capability to design and build custom
products where the flexibility of our platform-based processes
provides a responsive and competitive advantage. We offer isolators
in the Surface-Mount and Sub-Mount form factors. In addition, we
manufacture isolators with either an epoxy-free optical path or with a
laminated core. LightPath works with customers on the front-end to
tailor isolators for the manufacture of next generation products.

Many of today’s transmitters require optical isolators to eliminate
back reflections and feedback in the laser diode. This feedback
and noise creates jitters in the system. LightPath’s Tx™ Isolators
are manufactured in a very economical and scalable process.

The Tx™ Isolators are manufactured with a latched garnet,
which eliminates the need and extra cost associated with
traditional magnet. Latched garnet has the orientation of its
magnetic dipoles frozen by poling in an external magnetic field at
an elevated temperature.

Oasis™ Monolithic Isolator & Aspheric Lens
Oasis™ provides a compact solution by combining both
an aspheric lens and an isolator. Built as a monolithic
design, it offers diffraction limited performance optics
along with outstanding isolation. The designs are ideal
for small form factor laser diodes in both single and
multi-channel configurations.
Optical Isolators
The Surface Mount configuration offers smaller form
factors and exceptional value. The typical Surface Mount
Oasis™ contains a 0.55 NA Finite Conjugate lens that
couples a laser directly into a single mode fiber. As with
all of our products, LightPath offers extensive support
to our customers in designing and manufacturing
custom configurations. These would include a wide
selection of aspheric lenses and single, 1.5, and double
stage isolation.
