Motic Stereo zoom microscope SMZ171-TP, trino, 7.5x-50x (46455)

The SMZ-171 Series is a high-performance stereo zoom microscope designed by Motic to meet the needs of both routine and advanced research in biological, medical, and industrial settings. This series introduces enhanced optical quality and ESD-compatible materials, making it suitable for sensitive environments and a wide range of applications. The SMZ-171 delivers clear, distortion-free images with a strong depth of field, thanks to its Greenough optical system and a large 6.7:1 zoom range. Its modular design, wide accessory compatibility, and optimized LED illumination options make it adaptable for different laboratory requirements. The microscope is also easily upgraded for digital documentation by pairing it with a Moticam camera.

General Specifications

• Greenough Optical System

• Achromatic optics with anti-fungus treatment

• Widefield binocular or trinocular observation tube, 45° inclined (light distribution 0:100 right eyetube/trinotube in photo position)

• Widefield high eyepoint eyepieces WF10X/23 with diopter adjustment, +/- 5 dpt

• Interpupillary distance: 48-75 mm

• Zoom ratio: 6.7:1 with 5 clickstops

• Standard magnification: 7.5X-50X

• Working distance: 110 mm

Zoom Range

The 6.7:1 zoom ratio provides a standard magnification range from 7.5x to 50x. The parfocal optical design ensures that refocusing is unnecessary throughout the zoom range. Auxiliary objectives and eyepieces are available to extend the total magnification from 2.25X up to 200X.

Auxiliary Objectives

A standard working distance of 110 mm allows for comfortable sample manipulation at all magnifications. The maximum field diameter at the lowest zoom setting with 10X eyepieces is 30.7 mm.

Eyepieces

Widefield 10x/23 mm eyepieces are designed for comfort, including for spectacle wearers, and feature individual diopter adjustments of +/- 5 dpt. Alternative magnifications and measuring reticules are also available.

3-D Imaging

The Greenough system provides fully separated optical paths, resulting in high-quality, distortion-free 3D images. The system achieves a resolving power of up to 460 lp/mm with a 2x auxiliary objective.

Working Distance

The standard working distance is 110 mm and can be extended up to 301 mm with additional auxiliary objectives. Higher total magnification can be achieved by combining objectives less than 1X with high-magnification eyepieces.

Optical Heads

Available in binocular or trinocular versions with a 45° viewing angle, 10X eyepieces, and built-in 1X objective. The interpupillary distance is adjustable from 48 mm to 75 mm. A 60° binocular head is available for special setups. All optics are treated against fungus, making the microscope suitable for humid environments.

Modular Configuration

The SMZ-171 supports a modular system, allowing users to choose from classic pole stands, arm stands, or industrial boom stands for larger samples. ESD versions are available for electrostatic-sensitive environments.

Illumination

A variety of illumination options can be used with the SMZ-171, including ring lights for shadow-free imaging and cold light sources with light guides for detailed surface visualization.

Digital Documentation

Pairing the SMZ-171 with a Moticam digital camera transforms the microscope into a complete documentation and analysis station. The trinocular version supports different camera adapters for various chip sizes.
