We make it visible.


With OPMI Pentero, Carl Zeiss has created something unique: an ingenious simplification of complexity.


The Sum of

50 Years of Knowledge

The new Zeiss Pentero Microscope has exceeded all my expectations. The motorized X/Y movement; increased headroom; single-lever pistol grip movement; completely internalized video, cameras, and cables; elimination of the drape bulk with a vacuum system; single-button autobalance; and unparalleled binocular vision with superb lighting make this highly integrated microscope system the most important tool for the practice of neurosurgery.

For more than 50 years, Carl Zeiss surgical microscopes have been delivering excellence to the world’s most challenging professions.

Surgeons’ needs have been the driving force behind our quest to provide ever more refined, more multifunctional systems.

An OPMI is no longer just at the center of the microsurgical procedure, it is now an information and communication cockpit; not only the window to the operating field, but also a gateway to the outside world.

But how can a sophisticated, high-tech surgical microscope assist in simplifying very complex surgical procedures?

OPMI Pentero is the answer.




I have been using Carl Zeiss microscopes for the last two and half decades. They have provided the best in optics and have been constantly upgrading the technology. My team and I trust Carl Zeiss optics.

The challenge: to develop a new optical design that once again substantially improves depth of field, light and working distance.

Bringing it all within reach

State-of-the-art apochromatic optics deliver the legendary crystal-clear images, sharp details and natural colors associated with Carl Zeiss. The innovative optical design, with a new Varioskop, provides a larger working range and virtually ensures comfortable working conditions – even when using long instruments. The depth of field has been increased by 17 % and can be doubled by activating the DeepView function.

Bringing Light to the Darkness

Surgeons now have 20 % more light to work with, the assistant even more. Spot illumination precisely adjusts the light cone – all without reflections. The patented, two-channel illumination system delivers light wherever it’s needed – a distinct advantage, which provides higher-contrast images in narrow and deep canals.

Focus at the Push of a Button

The high-speed autofocus automatically delivers razor-sharp images at all times, regardless of magnification. And when focusing manually?

An intuitive laser-focusing aid assists in selecting the exact focal point – particularly helpful when using the mouth switch.

Stress Free

Whether the surgeon remains standing or seated, the 30 % more compact design of OPMI Pentero allows for freedom of hand and instrument movement while providing a short distance to the surgical field.

Thanks to its overhead design, the suspension system can be placed in any position – even behind the surgeon.

Maneuvring OPMI Pentero? Child’s play!

Whether using the handgrip or the mouth switch, the new movement system enables

OPMI Pentero to be effortlessly repositioned.

AutoBalanced at the Touch of a Button

The patented AutoBalance system provides outstanding balance with a single, simple touch of a button, regardless of the position of the microscope.

Robotic X/Y Movements

Fine and precise adjustments of the OPMI body are possible without even releasing the brakes – and without the usual limitations. OPMI

Pentero’s X/Y really can move in any direction.

Beauty and Functionality All in One

The new rotatable, easy-to-use video touchscreen has been perfectly integrated into the system. It intuitively guides the user through all functions.

Digital patient files allow instantaneous access to important information – even during surgery.

Various users can quickly retrieve their pre-programmed, personal settings.

The touchscreen also serves as a display for the integrated MediLive digital video camera. Its fullscreen mode eliminates the need for an additional video monitor.

Mouth switch


The Pentero is an operating microscope designed by surgeons for surgeons. It incorporates cutting edge technology in a compact, innovative and brilliant design. Carl Zeiss has combined efficiency, efficacy and ergonomics to create a microscope that brings neurosurgery and spinal surgery to an exciting new level.

Anticipates Your Every Desire


Carl Zeiss has created a virtual cockpit which allows me to access my information at any time. Everything

I need is displayed in the eyepiece at the push of a button.

How can a surgeon process the constant stream of diagnostic, navigation and system information without having to take his or her eyes off the operating field?

MultiVision TM

MultiVision enables the surgeon to superimpose color data into both eyepieces. Moreover, video data and the entire touchscreen interface can be injected into the MultiVision display and controlled using the joystick.

MultiVision provides a glimpse of where the

OPMI is heading.

Everything at a glance.

Touchscreen. View and control OPMI Pentero in the eyepiece.

Endoscope images. Endoscope towers are a thing of the past.

Surgeons can only treat what they can see – and Carl Zeiss enables them to see more.

OPMI Pentero is the world’s first surgical microscope to offer completely integrated support for fluorescence-based angiography and tumor resection.


The OPMI Pentero is a considerable advance in microscope technology. Especially its optional support for ICG-based angiography, 5ALA fluorescence-based tumor resection and digital video represent unique new tools for intraoperative diagnostics and documentation during microneurosurgical procedures.

Images of a resection cavity during an operation for glioblastoma multiforme as observed through the surgical microscope. Conventional white light illumination (3) is insufficient for distinguishing viable tumor margins. When enhanced using the fluorescence mode in combination with pre-operatively administered 5-ALA (4), the tumor extensions are more clearly delineated by their strong red fluorescence.

The fluorescence options are in compliance with the requirements of the European Medical Device directive 93/42/EEC. However, depending on national regulations, additional authorization may be required in the country in which the instrument and applications will be used.

The fluorescence options are not available in North America, Japan and other markets. Please contact your local Carl Zeiss representative for further information.

OPMI Pentero connects ...

... with colleagues around the world – via DICOM*, for example. But let’s start right here with the hospital network. OPMI Pentero can export or import patient data to other hospital computers via the network or DICOM interface*, e. g. preoperative data can be imported. An optional telephone* function further helps communication.

Navigation included

The navigation interface enables fast and easy connection to all leading navigation systems without external components and irritating wiring.

The Carl Zeiss open interface system permits the use of the same workstation and the same cable with other ZEISS surgical microscopes.

New and unique: binocular, color injection and superimposition of navigation data.

As a result of the innovative robotic X/Y design with three motorized axes, OPMI Pentero provides real tool tracking for viewing every point in the working and tilting range of the OPMI.

The laser-guided, high-speed autofocus system delivers precise navigation by focusing to a fraction of a millimeter and precisely identifying the displayed point.

And in case of an emergency?

We keep a vigilant eye on OPMI Pentero. Global, networked support centers provide 24/7 service and are supported by a help-desk database as well as a remote service function. Diagnosis and troubleshooting is carried out via the internet or telephone with assistance from the Service

Online Protocol.

With the launch of the OPMI Pentero, Carl Zeiss has introduced a totally new service concept for the surgical microscope. Our worldwide support and remote diagnostic capabilities are the benchmark in the industry. At Zeiss, meeting the needs of our customers is our number one priority.
