SMZ-161
Motic’s new SMZ-161 Stereo Zoom microscope joins the widespread success of the SMZ Stereo family by introducing light materials as well as a new, improved LED illumination options. Convincing optical performance, combined with a small footprint and robust mechanics, makes the SMZ-161 the ideal stereo microscope for teaching situations in High Schools and Universities. The Greenough optical system delivers clear and distortion-free images with an improved zoom range of 6:1. Parfocality is ensured while running through the complete magnification range; while a click-stop mechanism, implemented in the continuous zoom, enables precise reproduction of magnifications. The extended 110mm working distance in its standard configuration gives sufficient space for sample manipulation, using its convincing 3-dimensional upright image.
Zoom Range
With the SMZ-161, it is now both an easy and effortless task to step from a sample overview down to minute details. One precise rotation of the zoom knob gives access to the complete magnification range. The 6:1 zoom ratio delivers a standard magnification range of 7.5X-45X. Due to the parfocal optical design, a readjustment of the focus position is not necessary while zooming. To increase the model´s magnification range a complete selection of auxiliary objectives and eyepieces are available - extending the SMZ-161´s total magnification range from 2.25X up to 180X.
Auxiliary Objectives
The standard SMZ-161 configuration comes with a 110mm working distance, offering ample space for sample manipulation. The maximum field diameter (with lowest zoom position and standard 10X/20 eyepieces) is 26.7mm. Higher magnifications can be achieved by using the following auxiliary objectives,

Thanks to its compact dimensions and robust mechanics, Motic’s SMZ-161 is ideal for any kind of teaching application. Based on the Greenough Optical System with its completely separated viewing paths, the SMZ-161 delivers distortion-free 3-D images. Also further enhancing its image quality, multi-layered lens coatings deliver high contrast images with reduced internal reflections.
The Working Distance
With its standard configuration, the SMZ-161 provides a large working distance of 110 mm, which can be easily extended to 301mm (with additional auxiliary objective 0.3X). To achieve a desired total magnification, objective magnifications less than 1X may be compensated by using higher eyepiece magnifications
(up to 20X).
Standard Packages
Motic’s SMZ-161 optical heads come as Binocular or Trinocular versions, each with a 45° viewing angle, WF10X/20 eyepieces and built-in 1X objective lens. For special experimental setups or OEM inspection applications, a compact Binocular head with 60° viewing angle is also available. The anti-fungus treatment of all optics allows the use of the SMZ-161 in a variety of humid environments.
Modular Configuration
Besides the Standard packages, the SMZ-161 system also offers modular components for a personal configuration depending on the requirements of the workplace set-up. The industrial boom stands for larger viewing samples may replace the Plain and Transmitted light stands to increase user freedom significantly. All these stands require a separate illumination system following the requirements of the sample.
Illumination
Illumination is a critical issue to ensure the proper image rendering when using a stereo microscope. Motic offers a wide range of illumination options to be combined with the SMZ-161 optics. Especially for living samples in biology, Motic recommends LED illumination due to its negligible heat development and
minimized impact on living specimens. A more powerful solution is provided by the Motic Cold light source MLC-150. A variety of light guides for flexible illumination options are also available.
