Olympus SZX10 Stereomicroscope

A flexible imaging tool for routine research, the SZX10 stereo microscope offers darkfield and polarization imaging, a maximum numerical aperture of 0.2, a 10:1 zoom ratio, and a Galilean optical system that minimizes distortion.




Cost-Effective Performance and Accurate Image Reproduction

A flexible imaging tool for routine research, the SZX10 stereo microscope offers darkfield and polarization imaging, a maximum numerical aperture of 0.2, a 10:1 zoom ratio, and a Galilean optical system that minimizes distortion.



Flexible Stereo with Wide Zoom Ratio

Excellent Optical Performance with Natural View

The SZX10 is designed to provide a natural view of the specimen with excellent stereo and color representation. The DFPlan series combines high-NA resolving power and working comfort with "distortion-free" optical design for exceptionally flat imaging, and includes a 2x objective lens with an NA of 0.2 for high-resolution imaging at 600 linepair per millimeter.

Wide 10:1 Zoom Ratio

The SZX10 covers a magnification range of 6.3x to 63x with its 1x objective, and offers up to 123x magnification with a 2x objective. Thanks to this wide-ranging 10:1 zoom ratio versatility, it's a good choice for life science applications that require low-magnification macro views for dissection and specimen manipulation, and sharp high-magnification views for close observation of cell structures.

Digital Imaging and Documentation

The SZX10 can also be equipped with a trinocular tube and Olympus DP series digital camera for high-resolution imaging and research documentation. DP series cameras offer the high sensitivity for a wide range of applications, including high-sensitivity fluorescence imaging, and can be easily controlled using Olympus cellSens software.

Choice of Suitable Contrast and Observation Method


With a slim 41.5 mm design, that is approximately half the thickness of previous halogen lamp transmitted light illumination bases, new LED transmitted light illumination bases have a lower height to enable a low eyepoint and easy access to base-mounted samples during observation and operation. The LED illumination base SZX2-ILLTQ with quad position turret enables the user to choose cartridges and to switch from brightfield (standard/high/low), oblique (standard/high/low), darkfield, polarized illumination, and shutter with a simple turn. A one position LED illumination base is also an option (SZX2-ILLTS). This makes the SZX16 a flexible all-in-one microscope for various samples and observation tasks. Another advantage of LED illumination is a cooler base surface, which is suitable for long duration manipulation of live specimens. Power consumption is lower than a conventional 30W halogen light source. A life cycle of over 60,000 hours significantly reduces operation costs.

Choice of High-Performance Objectives


The DFPL series of objectives accurately reproduce specimen shapes with good color fidelity. 


Apochromatically corrected to achieve the highest degree of performance. Excellent in resolving power, contrast, and image flatness with small distortion. 


Provides well-balanced objectives that combines high resolving power with long working distance.



Simple Fluorescence Observation

With the addition of a fluorescence unit, the SZX10 can also be used to observe expressed fluorescence proteins within an organism. The unit's high-performance fluorescence mirror component offers fast startup and high fluorescence detection efficiency for improved image quality.

Ergonomic Observation Tube and Extendable Eyepoint Adjuster

The SZX2 series features observation tubes with an optimized convergence angle designed to enable users to make observations from a natural position that minimizes eye fatigue. This solution effectively eliminates eyestrain during long periods of observation. 
Our long tilting trinocular tube (SZX2-LTTR) improves the ergonomics of our stereo microscopes. This trinocular can be adjusted from 5 to 45 degrees to facilitate a more natural head and neck position while working. In addition, the eyepoint adjuster (SZX2-EEPA) enables users to raise or lower the eyepoint within a 120 mm range to accommodate users of different heights. The combination of these  help to reduce stress and fatigue by keeping users in a more natural posture while they’re working.
