MORE THAN MICROSCOPY

otic’s new SMZ161 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 SMZ161 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...

Eyepieces The SMZ-161’s standard Widefield WF10X/20mm eyepieces follow the high eyepoint principle, which allows spectacle wearers access to the complete field of view. A diopter adjustment of +/- 5 dpt is possible on both eyepiece tubes, while standard rubber eye guards minimize stray light and increase viewing comfort. The interpupillary distance can be adjusted between 50-75mm. Besides the standard WF10X/20 eyepieces, the SMZ-161 Series also offers alternative eyepieces: N-WF 10X (F.N.23), N-WF 15X (F.N.16) and N-WF 20X (F.N.13). For measuring purposes, a series of reticules are...

3-D Image Stereo microscopes have found numerous applications in biology, medicine and industrial quality control. The nature of the upright image of a stereo microscope is essential when manipulation work on living and “dead samples” occurs. Without the need for an often time consuming sample preparation, stereo microscopes are also ideal instruments for a first step into the “micro world” in education environments. 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...

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. The interlocking eyepieces can be adjusted within an interpupillary distance of 50-75mm. 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. The dovetail focusing mechanism of the SMZ-161 ensures smooth focusing and stable focus positions,...

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. A new slot/groove design improves the stability of the desired optics position without slant. And for easier transport, all new round/rectangle bases maintain an “easy hand-carrying shape”. All these stands require a separate illumination system following the...

Illumination Illumination is a critical issue to ensure the proper image rendering when using a stereo microscope. To reveal all possible information from the sample, a careful thought on illumination needs to be executed. Motic offers a wide range of illumination options to be combined with the SMZ-161 optics. The built-in illumination of the base stands provide the most compact and easy illumination option. Especially for living samples in biology, Motic recommends LED illumination due to its negligible heat development and minimized impact on living specimens. However, for more demanding...

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. light guide 1.5m length with standard straight distal end type Ring light guide 0 61mm light guide light guide 0.5m length with standard straight 0.5m length with standard distal end type straight distal end type

Accessories Especially when working with higher magnifications, handling samples becomes more sensitive to vibrations. For this, an appropriate solution to increase viewing comfort may be found within the SMZ-161’s optional stage accessories. Gliding stage For smooth multidirectional movement of the sample, a 360° rotatable gliding stage can be mounted onto the base plate of a Plain or Transmitted light stand. x/y-stage An attachable x/y-stage with 76X54mm travel range enables a precise bidirectional movement. Polarizer, Analyzer To analyze the birefringence of transparent materials, a...

Standard Photomicrography The adaption of a traditional single lens reflex camera (SLR), today mostly digital, requires a Trinocular version of the SMZ-161. The camera adapter consists of a mechanical part, to be combined with a 2.5X or 4X photo eyepiece. The necessary T2 adapter which connects to the camera’s bayonet mount-type is supplied by the respective camera manufacturer. This setup delivers high resolution images of small fields. Digital Documentation A more convenient setup is provided through Motic´s philosophy of easy image digitalization. The combination of a SMZ-161 with a...
