Integrating spheres are unique
tools used in many laser &
photonics applications. Gigahertz-Optik offers a wide range
of integrating spheres for both
detection purposes and for uniform light sources . To meet the
many varied application de-
mands, spheres with different
diameters are offered as well as
different coatings and measurement geometries. Besides the
modular UM series for light
measurements and uniform light
source set-ups Gigahertz-Optik
offers the UP series with pre-
cisely aligned port geometries for
reflectance and transmittance
measurements. Complete systems can be assembled using
accessory components and an
instrument from GigahertzOptik’s photometer, radiometer

Individual Sphere Design
Years of experience in manufacturing integrating spheres has
taught us that a line of standard
spheres will not fulfill all possible
customer needs. Most often
either the end-user accepts a
standard sphere as a compromise solution or must have the
stock item custom modified
adding extra cost and lead time.
The new UM integrating sphere
series allows individual integrating sphere set-up in the specific
configuration required with only
those components needed. An
added benefit to this design
freedom is that you don’t pay for
something you don’t need.
With standardized stock components and an innovative assembly process the UM series offers
economical prices and short
delivery times for integrating
spheres that others can only
claim as custom products.
Port frames with free apertures in
different diameters as well as
detector and light source ports

can be added and positioned on

UMB Basic Spheres are assembled using two hollow hemispheres made from aluminum
sheet stock.
The Orbit Flange located on
open side of each hemisphere is
used to mechanically mate the
sphere halves. The standard
position for the orbit flange is
vertical as shown in the above
drawing. But its actual position
can be specified at any angle
from vertical. Note that port
frames, sphere stands or other
accessory may limit the choice of
angle. 5 deg. angle steps with a
tolerance of +/- 5 deg. are recommended.
To specify position coordinates
for Accessory Components,
the same 5 deg. +/-5 deg. resolution is recommended. Position
can be mapped using the sideview ’SV’ and top-view ”TV’ angle
charts as shown above.
The sphere Al sheet forming
process only allows a typical
position tolerance of +/- 5 degrees.
For more precise alignment UP
series spheres are recommended.

UM Series “Set-up Examples”
Luminous Flux & Radiant Power Measurement of Spot Sources
The integrating sphere is the
preferred tool for the measurement of radiant power or luminous flux of spot sources with a
diverging light beam. Typical
examples of spot sources are
LEDs, LED panels, laser diodes,
fiber bundle light sources, reflector spot lamps, flat panel displays, endoscopes and others.
The reason why the integrating
sphere is preferable to a planar
detector is that typical photodiode detectors are limited in active area, size and acceptance
angle. Integrating spheres offer
large area measurement apertures and large acceptance angles in observance to the rule
that the ‘measurement aperture
area should not exceed 5% of
the total sphere area’. Temperature is another reason for using
integrating spheres in applications involving high power tungsten or xenon spot lamps. Large
diameter spheres are required to
maintain temperature within
operating limits, prohibit heat
damage and for stability/
accuracy of the measurement.
In this set-up a measurement
port and a detector port is
needed. Photometric, radiometric or colorimetric detectors can
be mounted onto the integrating
sphere with an accompanying
read-out instrument. In applications where wide variations in
sphere housing temperature may
occur, detectors with temperature stabilization are recommended to avoid drift of the
measured signal. A spectrometer
can also be used with or as an
alternative to the integral light
detector. Baffles are placed
between the lamp and detector
to prohibit direct illumination of
the detector by the incoming
signal.
The complete sphere system
can be calibrated in absolute
quantities such as luminous flux

UM Series “Set-up Examples”
Luminous Flux & Radiant Power Lamp Measurement
Measuring total radiant power or
luminous flux emitted by lamps is
one of the most common applications for integrating spheres.
Other than spot sources, lamps
emit light in all directions. The
integrating sphere collects all of
the emitted light entering it and
supplies an integrated signal to
its mounted light detector .
Lamps come in many different
form, size and output power
today. Examples include tungsten filament lamps, fluorescent
tube & bulb shape lamps, high
power xenon sources and many
more. Selecting the size of the
integrating sphere is typically
based on the maximum dimension of the lamp to be measured.
The sphere diameter should be
at least ten times the maximum
dimension of the lamp. For tube
lamps it should be twice the
largest dimension of the source.
For flux measurements a multidirectional lamp is placed in the
center of the sphere. Different
forms and sizes of sockets and
individual lamp holders are required for each different lamp
type. For smaller size lamps a
top-load port can be used for
insertion and removal. For large
size lamps integrating spheres
with a hinged frame allowing one
half of the sphere to fully open
are recommended .
Photometric, radiometric or colorimetric detectors can be
mounted onto the integrating
sphere with an accompanying
read-out instrument. In applications where wide variations in
sphere housing temperature may
occur, detectors with temperature stabilization are recommended to avoid drift of the
measured signal. A spectrometer
can also be used with or as an
alternative to the integral light
detector. Baffles are placed
between the lamp and detector
to prohibit direct illumination of
Miniature Lamp Measurement
the detector by the incoming
signal.
The complete integrating sphere
light detection system can be
calibrated in absolute optical
measurement quantities such us
luminous flux (lm), radiant power
(W) or spectral radiant power (W/
nm). Please refer to the Calibration Standards section for further

Uniform Light Source, Luminance and Spectral Radiance Standard
Uniform light sources are required to perform uniformity
calibration of imaging systems
and to calibrate luminance and
spectral radiance measurement
instruments.
Because of the integrating
sphere’s ability to produce multiple diffuse internal reflections
and a uniform illumination of the
inner sphere wall, it is the right
tool to form the basis for uniform
light sources.
Integrating spheres are available
in different diameters offering the
possibility for larger diameter
emitting windows.
A number of optional accessory
components can be added to
the integrating sphere to expand
its basic capabilities.
- Multiple lamps can be mounted
onto one sphere offering high
flexibility in intensity level.
If each lamps is operated with its
own power supply, intensity can
be varied in steps by simply
switching light sources on and
off.
- External spot lamps can be
combined with variable attenuators to control the light output
intensity in small steps. Attenuators with different resolutions
are available.
- External spot lamps can also
be combined with manually exchangeable filters used for both
neutral density attenuation and
for forming the emission spectrum purposes.
- Remote control filter wheels
and attenuators are another
option to build a completely
automated system.
- A large dynamic intensity range
can be realized by combining
neutral density filters with a variable attenuator.
- Extra band pass filtering allows
uniformity calibration across
different wavelength ranges.
Large Aperture Uniform Light Source
- High speed shutters as fast as
40 ms enable calibration of the
lamp’s on/off characteristic.
- Luminance and spectral radi-
ance calibration is available
through GO’s calibration lab (ISO
EN 17025 accredited for spectral
irradiance & sensitivity).

UM Series “Set-up Examples”
Multi-port Configurations for Reflectance, Transmittance, Absorbance
Integrating spheres offer unique
functions which makes them very
useful in reflectance, transmittance and absorbance applications.
The Lambertian emittance
characteristic of uniform light
sources incorporating integrating
spheres provides a hemispherical diffuse and uniform illumination of test samples e.g. such as
light panels used for backlighting
of displays.
In this case the luminance contrast of the light panels can be
measured using an additional
luminance meter viewing through
an additional port.
The large acceptance angle of
integrating sphere based light
detection systems is the main
reason for using spheres in reflectance and transmittance
applications.
Any light that is reflected by a
diffuse material or passing
through a diffuse material must
be completely detected. This
should be independent of the
angle of reflected or transmitted
light and also from any increase
in spot size. Flat field detectors
do not meet this requirement.
The port frame will not interfere
with the acceptance angle if it is
designed with a knife-edge.
Besides acceptance angle, larger measurement apertures can
be made, an other argument for
the integrating sphere.
A precisely collimated light
beam is a prerequisite for accurate reflectance and transmittance measurements. The collimated beam must not only
precisely target the
sample area but also
not contain any diffraction rings
which can produce an offset light
level inside the sphere limiting
Reflectance & Transmittance
measurement resolution.
Consider the UP series integrating spheres for reflection, transmission, absorbance and other
applications where more precise
port positioning is critical.

Integrating Spheres - Page 107
UP Series
Precision Machined Integrating Spheres
In cases where a high precision
spherical form and precise alignment of sphere ports is critical,
machined integrating spheres
are a better choice than spheres
formed out of aluminum sheets.
In smaller diameter spheres the
spherical shape is important to
produce a uniform light distribution inside the sphere.
Precise port alignment is a requirement in all kinds of transmittance, reflectance and absorbance measurements. Exact port
positions produce optimum
sample illumination and more
accurate measurement of directional reflection and transmission.
Three different coatings are offered for UP Series Spheres:
1. UPB Barium Sulfate
2. UPG Gold
3. UPK OP.DI.MA.
Three different standard port
arrangements are offered:
–L type spheres are designed
for the measurement of directional emitting light sources. A
knife-edge measurement port
opening offers a large acceptance angle for diverging light
sources. Special baffle designs
prevent any direct or first reflection illumination of the detector.
–F type spheres are designed
for flexible use in measurement
of reflectance (8°/D), transmittance and power. The knife-edge
design of the measurement port
ensures that any diffuse reflected
or transmitted light enters the
sphere. The back side ports
allow 8° sample illumination. To
measure diffuse reflection, the 8° port can be opened so that
directional glow radiation can
pass out. Special light traps are
offered. The back-side central
port permits the separation of
diffuse and directional transmitted light. An additional substitution port may help to reduce the
substitution error during calibration and measurement. The
back-side and substitution ports
are supplied with coated port
plugs (same coating as used in
sphere).
-US type spheres for uniform
light source set-up based on
LEDs.

Barium sulfate is an economical coating offering a ~ 97 %
(600 nm) diffuse reflectance
characteristic within the wavelength range from 300 nm to
2400 nm. For photometric applications the reflectance can be
reduce to ~ 80 % to reduce
substitution effects errors produced by high reflectance.
8100 10200 12750 18000
OP.DI.MA. is Gigahertz-Optik’s
own white plastic with an excellent diffuse reflectance characteristic and high durability.
Its diffuse reflectance is close to
that of a perfect lambertian reflector ensuring a highly uniform
light distribution across the inner
walls of the integrating sphere.
The spectral reflectance covers a
wide spectral range from ultraviolet to IR, 250 nm to 2500 nm
with > 95 % reflectance and a
peak reflectance of > 98 % in
the VIS/NIR spectral range.
UPK-100-L
UPG: Spheres with Gold Coating
Uncoated gold outperforms all
other uncoated metallic reflectors at infrared wavelengths.
Gold’s high reflectivity in the red
portion of the visible spectrum is
apparent by it’s yellow hue.
With a reflectance of ~ 95 % in
the wavelength range from 800
nm to 20 µm, gold is the best
choice for surface coating of
integrating spheres used in IR
applications. A proprietary interior surface preparation creates
the diffuse reflectivity required for
uniform light distribution inside
the sphere .

The UPK-30-L is a compact 30
mm (1.2 in.) diameter integrating
sphere with OP.DI.MA. coating.
The small diameter and high
reflectance of 98 % in the wavelength range from 400 to 1700
nm result in a low attenuation
which allows to build high sensitive sphere detectors with small
area and therefore low price Si–
and InGaAs photodiodes. The
unique baffle design combined
with the good diffuse reflectivity
of ODM98 makes this sphere
insensitive against different light
incident angles and reduces
effects by polarization and rereflected light. One, alternative
two 11-type detectors or UFC
fiber connectors can be assembled.

The UPK-50 is a very popular
compact size integrating sphere
for many radiometric and photometric applications requiring
sphere mounted integral detectors or diode array spectrometers.
The OP.DI.MA. coating is highly
reflective from 250 nm to 2500
nm. In combination with its small
50 mm (2 in) diameter a low
attenuation factor results which
makes the UPK-50 series ideal
for sensitive measurement applications.
The nearly ideal lambertian reflectance characteristic of
OP.DI.MA. offers best light distribution by the multiple reflections,
which is very important for small
diameter spheres.
The knife-edge and unique baffle
designs plus good diffuse reflectivity enable a large measurement port acceptance angle.
Model UPK-50-L is designed to
measure the intensity of directional light. One or more detectors, or alternatively fiber optics,
can be adapted to the sphere to
increase the wavelength range.
Model UPK-50-F is a more
flexible version for reflectance
and transmittance measurements. One or more detectors,
or alternatively fibers, can be
adapted to the sphere to increase its wavelength range.
Model UPK-50-ULS is designed for uniform light source
set-ups using multiple standard
LEDs.

Light Sources
Light sources are needed in application where integrating

light sources or in reflectance
transmittance measurements.
Gigahertz-Optik offers three
different kinds of light sources as
well as lamp power supplies and
stepping motor drives for accessories used with light sources.
LS-IS1.5
Integrating spheres are the ideal
tool to build uniform light sources. The most economic way to
set-up a uniform light source is
to place lamps inside of the
hollow sphere and baffle them
against the light output port.
One or more LS-IS1.5 can be
mounted to the UM spheres to
reach the expected luminance
level at the output port.
The lamp housing of the UMLSIS is compact and easy to assemble to one of the UMPF-1.5

LS-OK30 Light Source Series
LS-OK30 assembled to UPK-190
In applications were the light
output intensity of a uniform light
source needs to be controlled or
the light has to be spectrally
filtered the light source needs to
be placed outside of the sphere
to allow to place a variable aperture and/or optical filter between
lamp and hollow sphere.
The LS-OK offers an unique
reflector design which increases
the intensity and uniformity of
their light output. This reflector
does also work like a ’simple
satellite sphere’ which effects an
increased uniformity.
Different lamps from 10 to 100 W
radiant power are offered. The
electrical connection is done by
banana jacks.
Fan’s, direct to the lamp housing
reduces the operation temperature of the lamp socket.
LS-OK30-VA with 1:6 gear drive
and LS-OK30-MIR with a micrometer drive work as variable
attenuators if they are placed
between lamp and sphere.
