Stemi 305

Stemi 305 is your compact stereo microscope with a 5:1 zoom – equally at home in the biology classroom, research lab or on the industrial shop floor. Choose between predefined microscope sets to get the optimal illumination equipment for your applications. Stemi 305 lets you observe samples as they really are: three-dimensional and crisp in contrast – no preparation needed. Enjoy all the advantages of an easy-to-use microscope with integrated LED illumination for reflected and transmitted light – plus fast, easy-to-use documentation. This Greenough microscope will give you crisp 3D impressions, versatile object illumination and easily acquired images to share, whenever you want.
All-In-One Device
Stemi 305 integrates everything you need – various illumination and documentation. This compact Greenough stereo microscope comes without additional boxes and cables - just plug it in and switch it on, that’s it the installation is done. Stemi 305 can easily be operated, even by untrained users. All you have to do is illuminate your object, focus and start snapping images.
Integrated Illumination
Easily select and mix the integrated LED illuminations: near vertical and oblique reflected light, so as transmitted light. White LEDs generate bright light of day­light color, so each image appears crisp and clear. You profit from long lifetimes and low energy consumption. LEDs stay cool and they are noiseless and maintenance free.

Axio Zoom.V16

Axio Zoom.V16, the apochromatic on-axis zoom microscope by Carl Zeiss, delivers both high resolution and a zoom range of 16x. With its large working distance and a single objective, you will be zooming seamlessly from large object fields to the smallest detail. Large tile-images at low to medium magnification rates are a special strength, enabling you to enjoy the speed and ease of auto-mated stitching. The objective aperture of Axio Zoom.V16 is big compared to stereomicroscopes and leads to resolution rates that are clearly better, particularly at low to medium magnification. Imaging is a lot faster: Capture images more efficiently and speed up your quantitative analyses.
Zoom between minute detail and large object field
Your Axio Zoom.V16 combines its 16x zoom with a high numerical aperture and large working distance: even at low and medium magnifications you will achieve resolutions up to twice as high as with conventional stereomicroscopes. Don’t waste your time stitching tile-images: now you can image entire components with just a few shots. Work up to four times faster, achieve results in a more effective way and reduce sources of error.
The zoom microscope that is made for your application
Axio Zoom.V16 works with a motor-driven iris so you can select the ideal mode for your application at the touch of a button. Brightness Mode captures your images with the highest possible intensity across the whole zoom area. Use Eyepiece Mode when you want to analyze your samples visually through the Axio Zoom.V16 eyepiece. Zoom from large object fields with a maximum depth of field in high magnifications, achieving the highest possible resolution. In Camera Mode, your Axio Zoom.V16 automatically matches the resolution to the performance of your camera. Throughout the whole zoom range, Axio Zoom.V16 chooses the best ratio between resolution and depth of field.
With Axio Zoom.V16, you have an overview of entire components. Then, magnified 50 times, the geometric architecture of the electrodes becomes visible. You will see details such as the layer thickness of the active material, arresters and separators. Use these detailed insights to draw conclusions about manufacturing defects.
During forensic analyses, examine traces that lie deep in projectile cases. Thanks to the high resolution of your Axio Zoom.V16, you will capture them in every detail. The coaxial incident light minimizes reflections. You can document even the faintest traces with great reliability. Use the software module Extended Depth of Focus (EDF) to produce an image covering the entire thickness of your specimen – EDF processes sharp images full of details out of several focal planes.
