Motic’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 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.

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).

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 magnifica- tion range. Defined click-stop positions within the continuous zoom range allow exact magnification reproductions, a necessary precondition for reproducible calibrations and precise measure- ments when reticules or digital tools are used.
The 6:1 zoom ratio delivers a standard magnification range of 7.5X-45X. Due to the parfocal optical design, a re-adjustment 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.
3D 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 separated viewing paths (a proven concept time-tested for more than 100 years), 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.
Auxiliary Objectives
The standard SMZ-161 configuration comes with a 110mm work- ing 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, (following even ESD requirements):
| Magnification | W.D (mm) | Max Field Diameter (with 10X20 Eyepiece) |
|---|---|---|
| 1.5X | 56.3 | 17.8 |
| 2X | 38.6 | 13.3 |
A larger sample overview is possible by choosing the following auxiliary objectives:
| Magnification | W.D (mm) | Max Field Diameter (with 10X20 Eyepiece) |
|---|---|---|
| 0.3X | 301 | 88.9 |
| 0.5X | 191.8 | 53.3 |
| 0.63X | 142.7 | 42.3 |
| 0.75X | 128.6 | 35.6 |

Modular Configuration
Besides the Standard packages, the SMZ-161 system also offers modular components for a personal configuration depending on the require- ments 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 requirements of the sample.
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 applications, a more powerful or variable solution may be necessary. A ring light might be required for a shadow-free image, while the visualization of a surface structure may need a unidirectional illuminator by combining a cold light source with a light guide.
Optional ring lights are:
2401K Fluorescent ring illumination 220V/12W 6400K color temperature (CE)
LED ring illumination 60T-B dimmable +/- 6800K color temperature (CE)
LED ring illumination 60T dimmable and segmentable +/- 6500K color temperature (CE)
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.
Flexible PVC sheating light guide
1.5m length with standard straight distal end type
Ring light guide Ø 61mm
1m length with Ø 61mm distal end
Gooseneck 1-Arm light guide
0.5m length with standard straight distal end type
Gooseneck 2-Arm light guide
0.5m length with standard straight distal end type
Accessories
Especially when working with higher magnifications, handling samples be- comes 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 bidirec- tional movement.
Polarizer, Analyzer
To analyze the birefringence of transpar- ent materials, a polarizing set-up is re- quired. The respective polarizer/analyzer combination for the SMZ-161 is fixed on top of the light exit of the transmitted light stand.
Darkfield insert
For Darkfield applications, a special DF insert is mounted on top of the light exit of the Transmitted light stand. The iris diaphragm allows variation of the illumi- nation aperture according to the nu- merical aperture of the objective in use.
Digital Documentation
A more convenient setup is provided through Motic ́s philosophy of easy image digitalization. The combination of a SMZ-161 with a member of the Moticam Series of digital cameras delivers excellent live images, which can easily be stored for future usage. All Motic cameras come equipped with software to transform the SMZ-161 into an analysis and documentation workstation. For the Binocular SMZ-161, multiple eyepiece adapters for Motic cameras are available. The Trinocular SMZ-161 allows the use of different camera adapters, depending on the chip size of the camera in use. Motic offers a complete range of digital cameras, starting with a basic resolution of 1MP (CMOS) up to the research grade Moticam Pro Line (CCD) with a range of 1 megapixel and beyond, including Monochrome and Cooled versions where necessary. These Moticam cameras deliver sharp live images with an all-inclusive software package for easy post-capture handling, measurement and annotation. For further details on our range of cameras, as well as on adaptation questions, please contact your nearest Motic office or your local authorized Motic Professional reseller.
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.
