SMZ-171 Series Overview

The SMZ-171 Stereo Zoom Microscope represents an enhanced addition to Motic’s established SMZ Stereo series. This model incorporates new materials for ESD compatibility and optimized LED illumination options, making it a versatile platform for a variety of biological and material science applications. Its advanced optical performance and broad accessory range make it suitable for both routine and research tasks, from biological and medical sample preparation to industrial quality control and inspection. The SMZ-171 delivers consistently clear, distortion-free images, thanks to its Greenough optical system, which features a 6.7:1 zoom range and parfocality at all magnifications. The 5-position click-stop mechanism within the continuous zoom system allows precise magnification settings for repeatable measurements. With a standard working distance of 110 mm, there is ample space for sample viewing and manipulation. Enhanced depth-of-view ensures sharp, three-dimensional upright images. The SMZ-171 can also be easily converted into a documentation station by pairing it with a Moticam camera.

• Working distance: 110 mm

Zoom Range

The SMZ-171 enables seamless switching from macro to micro views with a 6.7:1 zoom ratio, offering a standard magnification range of 7.5x to 50x. The parfocal optical system eliminates the need for focus adjustment while zooming. Auxiliary objectives and eyepieces can further extend the total magnification range from 2.25X up to 200X.

Auxiliary Objectives

With a 110 mm working distance, the SMZ-171 provides sufficient space for sample manipulation at various magnifications. At the lowest zoom setting with 10X eyepieces, the maximum field diameter is 30.7 mm.

Eyepieces

The standard widefield 10x/23 mm eyepieces are designed for comfort, even for users who wear glasses. Each eyepiece has an individual diopter adjustment (+/- 5 dpt), and rubber eye guards help reduce stray light and improve viewing comfort. The series also offers eyepieces with different magnifications and a range of reticules for measurement.

Three-Dimensional Imaging

The Greenough Optical System, with fully separated optical paths, delivers impressive, distortion-free 3D images and high resolving power, up to 460 lp/mm with a 2x auxiliary objective.

Working Distance

The standard configuration provides a working distance of 110 mm, which can be extended to 301 mm with an additional auxiliary objective. Lower objective magnifications can be compensated for by using higher magnification eyepieces, up to 20x.

SMZ-171 optical heads are available in binocular or trinocular versions with a 45° viewing angle, 10X eyepieces, and a built-in 1X objective. The interpupillary distance can be adjusted from 48 mm to 75 mm. For specialized applications, a binocular head with a 60° viewing angle is available. All optics are treated to resist fungus, making the microscope suitable for humid environments. The SMZ-171 can be mounted on various stands, including classic pole stands (32 mm diameter) and new arm stands, both available in ESD versions for electrostatic-sensitive environments.

Modular Configuration

The SMZ-171 offers a modular system to accommodate different workplace needs. Industrial boom stands can be used for larger samples, replacing base stands and increasing flexibility. All stands require separate illumination systems tailored to the sample.

Illumination

Proper illumination is essential for stereo microscopy. The SMZ-171 supports a range of illumination options, including ring lights for shadow-free imaging and unidirectional illuminators for highlighting surface structures, using a cold light source and light guide.

Digital Documentation

The SMZ-171 can be combined with Moticam digital cameras for live imaging and documentation. All Motic cameras include software that transforms the microscope into a workstation for analysis and documentation. The trinocular version allows the use of different camera adapters, depending on the camera’s chip size.
