Stereo Microscope

Stereo Microscope he SMZ168 Stereo Zoom microscope represents the top-of-the-line model in Motic’s successful SMZ Series of stereo microscopes. Designed for a wide range of biological and material science applications, the SMZ168’s optical quality and versatile accessories will satisfy the most demanding user applications in both routine and research fields. From industrial quality control to biological preparation work, the SMZ168 is a durable workhorse model ready for a variety of applications. Its Greenough optical system comes with a large zoom range of 6.7:1, parfocal at all...

Zoom Range With the SMZ168, changing from a macro sample overview down to viewing micro details becomes an easy task. With one rotation of the zoom knob, the complete magnification range can be easily accessed. Five defined click-stop positions within this continuous zoom allow exact reproduction of magnification, a necessary precondition for precise measurements - especially for critical measurements done by reticules or digital cameras. The standard configuration of a 6.7:1 zoom ratio enables a total magnification of 7.5X-50X. No need for re-adjusting the focus while changing the zoom...

Auxiliary Objectives The standard configuration of the SMZ168 has a working distance of 113mm, offering sufficient space for sample manipulation under the microscope. The maximum field diameter (with lowest zoom position and 10X eyepieces) will Higher magnifications can be achieved by using the following auxiliary objectives: To get a larger overview the customer may choose between the following options:

Eyepieces The SMZ168’s standard Widefield 10X/23mm eyepieces come with rubber eye guards to minimize stray light, while increasing viewing comfort for the user. The high eyepoint principle of these eyepieces provides spectacle wearers a sharp and true colour image over the complete field of view. Spectacle wearers will also appreciate the diopter adjustment of +/- 5 dpt on each eyepiece tube. Beside the standard 10X eyepiece magnification, the SMZ168 Series also offers eyepieces with alternative magnifications: Measuring Eyepieces For more detailed measuring applications, a series of...

3-D Image Stereo microscopes have a wide variety of uses in numerous professional applications such as the life sciences, industry, as well as in areas of botany or mineralogy. The upright image of a stereo microscope is perfect for manipulation work on the specimen; while there is no need for a special preparation of the sample. Motic’s SMZ168 is based on the Greenough Optical System, an optical concept proven for more than 100 years in microscope history. With separated optical paths for both eyes, the SMZ168 delivers impressive 3-D images, distortion-free, with an uncompromised high...

The Working Distance Sample manipulation is a major activity when using a stereo microscope. For this, the SMZ168’s extended working distance will help practitioners when using tweezers, needles or similar dissection tools. With its standard configuration, the SMZ168 provides a large working distance of 113 mm, which can be easily extended to 324mm (with additional auxiliary objective 0.3X). Objective magnifications lower than 1X may be compensated by using high magnification eyepieces (up to 32X). Example: Standard configuration, eyepieces 10X, max. zoom position: Total magnification 50X...

Standard Packages The standard packages of Motic's Trinocular versions with 35° viewing angle, 10X eyepieces and standard IX objective. For Industrial inspection or OEM applications, a special Binocular zoom body with 60° viewing angle is Both standard zoom bodies can be combined with a Plain stand (without illumination) or with a Transmitted light stand, integrating an incident & transmitted light illumination. The incident/transmitted light stand may come with 12V/10W Halogen or 3W LED, which can be activated separately Binocular Zoom Body 0 0 Trinocular Zoom Body Head holder/focusing...

Modularity Besides the standard packages, the SMZ168 also offers a modular component system so that the instrument can be configured according to personal preferences and requirements. Stands, optical setup with objectives/eyepieces and further accessories can be combined to freely build to the end-users application requirements. For larger viewing samples, the standard Plain or Transmitted light stands can be replaced by one of the following stand options, which all increase user freedom. All these stands require a separate illumination system following the requirements of the sample. 1....

Illumination Illumination is one of the most critical elements for the proper use of a stereo microscope. To meet these illumination needs, Motic offers a wide range of illumination options to be combined with the SMZ168 optics. The built-in illumination of the basic stands, whether Halogen or LED, provide the most compact and easy illumination options. Especially for living samples in biology, LED illumination is preferred due to minimal heat development, resulting in minimized impact on the specimen. However, for more demanding samples, a more powerful or variable solution may be...

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. MLC-150 Fiber optic illuminator • 21V/150W Halogen Illumination • Switching power supply 100-240V (CE) • Local/remote switch for intensity control • Color temperature LED read out Available Light guides for MLC-150: Ring light guide Ø 61mm light guide light guide light guide 1.5m length with standard 0.5m length with standard straight 0.5m length with standard straight distal end type straight distal end type

Accessories Especially when working with higher magnifications, handling samples becomes more difficult. For these demanding samples, an appropriate solution to increase viewing comfort may be found within the SMZ168’s optional stage accessories. Gliding stage For smooth multidirectional movement of the sample, a 360° rotatable gliding stage is available. This stage is mounted onto the base plate of a Plain or Transmitted light stand. x/y-stage with rotatable insert An attachable x/y-stage with 76X54mm travel range enables a precise bidirectional movement. A rotatable insert is available as...
