SMZ-171 Series

With the new SMZ-171 Stereo Zoom microscope Motic proudly introduces an optically improved addition to its well-established SMZ Stereo series. New materials for ESD compatibility as well as optimized LED illumination options have been added to this series to create a versatile Stereo microscope platform for a wide range of biological and material science applications. The SMZ-171’s optical performance, combined with its expanded accessory line, make it an ideal instrument for the demanding requirements for both routine and research fields. From biological and medical preparations to industrial quality control and inspection, the SMZ-171 will deliver repeatedly clear and distortion-free images. The Greenough optical system comes with a large-scale zoom range of 6.7:1, parfocal at all magnifications; while a 5-position click-stop mechanism, implemented in the continuous zoom, enables precise reproduction of magnifications for easy measurements. The working distance of 110mm in its standard configuration gives sufficient space for any kind of sample viewing and manipulation. Also, an enhanced and crisp depth-of-view produces consistent and convincing 3-dimensional upright images. Further, the SMZ-171 can convert easily into a complete documentation station by combining it with a member of the Moticam camera family.

Details

Zoom Range

Switching from a macro overview down to micro details has never been easier than with the SMZ-171. The 6.7:1 zoom ratio in the SMZ-171 enables a standard magnification range of 7.5x-50x. While zooming, a re-adjustment of the focus position is not necessary - as the complete optical system is designed for parfocality through the complete zoom range. To increase the model´s magnification range a selection of auxiliary objectives and eyepieces are also available, extending the SMZ-171´s total magnification range from 2.25X up to 200X.

Auxiliary Objectives

With a standard working distance of 110mm, the SMZ-171 offers sufficient space for sample manipulation through various magnifications. The maximum field diameter (with lowest zoom position and 10X eyepieces) will be 30.7mm.

Eyepieces

The SMZ-171’s standard Widefield 10x/23mm eyepieces follow the high eyepoint principle, giving spectacle wearers access to the complete field of view. Individual eyepiece diopter adjustments of +/- 5 dpt provide the best conditions for the use of reticules, while standard rubber eye guards minimize stray light and increase viewing comfort. Besides the standard 10X eyepiece magnification, the SMZ-171 Series also offers eyepieces with alternative magnifications. For measuring purposes, a series of reticules are available.

3-D Image

Motic’s SMZ-171 is based on the Greenough Optical System. With its completely separated optical paths, this system has been a proven concept for more than 100 years of microscopy. The SMZ-171 delivers impressive 3-D images, distortion-free, and with a high resolving power of maximum 460 lp/mm (with 2x auxiliary objective).

The Working Distance

With its standard configuration, the SMZ-171 provides a large working distance of 110 mm, which can be easily extended to 301mm (with additional auxiliary objective 0.x). To achieve a desired total magnification, objective magnifications less than 1X may be compensated by using high magnification eyepieces…
