LEICA S9E/D/I/SAPO Stereo Microscopes

Continuously improving production, keeping defect rates low, and fulfilling customer requests in order to stay competitive can be very challenging. Leica has developed the S9 stereo microscope series to help you cope with these challenges.




S9 Series Greenough Stereo Microscopes

Save up to 20% inspection and rework time*

Continuously improving production, keeping defect rates low, and fulfilling customer requests in order to stay competitive can be very challenging. Leica has developed the S9 stereo microscope series to help you cope with these challenges. With this generation of Greenough stereo microscopes operators will be able to reveal details faster as they spend less time having to adjust the microscope.

*compared to the standard industrial stereo microscope S6 from Leica



Optimize optical inspections

Available in different versions for diverse needs the S9 stereo microscopes boost efficiency and optimize optical inspections in your production line or Quality Control division, due to:

  • FusionOptics technology with 12 mm depth of field to find details fast
  • High magnification up to 55x and 9:1 zoom for quick changes from overview to details
  • 122 mm working distance for easy sample manipulations under the microscope
  • Integrated, network-camera for easy image sharing

Find details faster with 3x more depth of field

Move the slider and see for yourself how FusionOptics combines larger depth of field with maximum resolution to deliver an amazingly sharp yet highly detailed image, that is impossible to see with other standard stereo microscopes.

With 3x larger depth of field, microscope operators can save time refocusing as they now see every important detail at a glance.

(Note: Image simulation, showing a printed circuit board sample without and with the FusionOptics effect, perceived when looking through the oculars.)

Quick magnification change

Operators can effortlessly switch from overview to detail with the uniquely high 9:1 zoom, speeding up inspection and manipulation.

Apo corrected zoom optics with 55x magnification reveal new details in your sample. 

With fewer adjustments of zoom or focus, operators’ concentration on the sample is higher, as they face less interruptions. Throughput will increase naturally.

Quick magnification change


Easy sample manipulation with maximum working distance

Sample inspection and manipulation under the microscope can be conveniently performed with the 122 mm working distance of all S9 stereo microscopes.

Enjoy working with more space for your tools under the microscope lense – sometimes every mm counts.

The S series from Leica: S9 and S APO


S9 E for analog inspections
S9 D with documentation port
S9 i with integrated camera for digital image sharing
S APO with 80x magnification for easy screening and sorting


S9 i with integrated camera

Get connected for faster results

Enjoy working with HD-microscope images live streamed to your PC, HD-monitor, or mobile device. The S9 i stereo microscope has an integrated 10 MP CMOS-camera and can be connected with your facility’s network by Ethernet.

This gives you the opportunity to quickly react to queries, get a second opinion, and discuss problems e.g. via tablet with others.

Results can be documented quickly and reliably in video or image format.

The S9 i delivers real-time images with up to 35 frames.



S9 D with documentation port

Ready for digital imaging when you are

The S9 D gives you the flexibility to add a camera to the microscope and turn it into a digital microscope solution. The built in 50:50 split of the beam path allows oberservation through the eyepieces and digital imaging at the same time.

Digital functionality provides advantages, when

  • Training operators
  • Sharing results with others
  • Getting a second opinion 
  • Analyzing and measuring details in a sample
  • Documenting results 

The integrated documentation port allows connection to a range of Leica microscope cameras.



S9 E for inspection and rework

Boosting workflow routines 

For analog microscope inspections the S9 E is an indispensable asset. It provides a cost effective solution with fast return on investment.

Like all other S9 stereo microscopes it offers:

  • 12 mm depth of field and FusionOptics technology for a natural viewing perception and fast results
  • 6.1x-55x magnification and a 9:1 zoom range for quick changes from overview to details
  • 122 mm working distance for convenient and ergonomic manipulations under the microscope
  • Click-stops to work with reproducible zoom settings
  • Apochromatically corrected optics to reduce color fringes



S APO unique Greenough Stereo Microscope with high magnification power

The Greenough stereo microscope, S APO with apochromatic 8:1 zoom and high magnification up to 80x is ideal for quality control, cell sorting, and microinjection applications.

With 75 mm working distance it provides easy access to the sample. An ergonomic viewing angle of 38 degrees allows comfortable posture, which helps to increase productivity and reduce fatigue related inspection errors. Adjustable zoom stops allow fast, easy, repeatable measurements and inspections. 

The integrated documentation port allows connection of a digital camera.




Changing perspective is easy

Do you sometimes find it difficult to work only through the eyepieces of the microscope?

With the digital functionality of the S9 i, S9 D, and S APO you don’t have to choose between screen or eyepieces.

You can quickly scan through samples using a large screen view and check on details through the eyepieces of the microscope.

Changing perspective is easy


Working efficiently in life science research with S9 stereo microscopes

From specimen dissection and preparation to sorting and screening of model organisms, S9 stereo microscopes boost your workflow efficiency in life sciences.

  • See more in Z: Exclusive FusionOptics technology from Leica provides high resolution with high depth of field, with 9:1 zoom, 6.1x-55x magnification, 250 lp/mm resolution and 122mm working distance.
  • Easy training: Camera-ready or integrated camera configurations add versatility for training and sharing.
  • Easy documentation: Leica software is included for quick, easy, and repeatable measurements and documentation.

S9 i - Compatible with TWAIN

TWAIN is a protocol that enables communication between software and selected Leica Microsystems microscope cameras. It allows you to process images with your preferred software later on. 

Take advantage of your camera’s TWAIN capability to control the camera, acquire images, and transfer image data to various repositories for analysis and archiving. For example, easily store images to your Laboratory/Hospital Information Management System (LIS/HIS/LIMS).
