20 Most Recent Zeiss Microscope Questions & Answers

Field of view and working distance vs magnification is a law of physics. Using the lowest power gives you the widest field of view and greatest working distance but the trade of is that you loose magnification. Conversely as you increase magnification you decrease working distance and you loose field of view diameter.
The optics of your microscope are limited to .4x to 2.5x magnification. Your working distance is limited to 200 - 400mm depending on the magnification you are using.
I am not aware of any interchangeable lenses for this scope.

Generally speaking, without knowing much exactly what you have, there is a possibility that you could be missing a lens. It is hard to say though without asking you a 100 questions. The lens cell in front of the camera is designed to shrink down the square sensor of the camera, so that it can fit with in the round hole of the optics. Most adapters Will have several lens, which will depend greatly on the size of the sensor or how much it need to reduce it by. If there are no lenses then it would look like the camera is looking down a tube, and there will be shadowing or darkness all the way around your image.

If a single lens is missing then you would most likely get a sphere on light or very intense hot spot in the center of the field of view. It is really hard to describe what this would look like, but if you where able to see an image through it, it would appear to be bowed. With a photo, I could tell you for sure.

There are also other variables unrelated to the camera and adapter that might causes this, such has the position of the condenser (try adjusting the height), or you can also control this a bit by adjusting your iris. If this only occurs on the higher magnification, do you notice any changes in through the eyepieces. Sometimes if immersion old gets inside of one, it can act like an additional lens, and do all sort of crazy things.

When trouble shooting you need to determine which variables are at play. For instance do you only see it on one magnification, or is it only on low and not high. Is the hot spot seen through only the camera, or can you see if through the eyepieces as well? Each one of those question will help you start to isolate down where the problem is.

For instance if you know that it occurs on all magnifications, then you know you can rule out the objectives as the problems. If you can see it through both the eyepieces and camera, then you can rule out the camera and the adapter. If seen at higher magnification and not lower, than it is most likely not a condenser problem.

If you see it at lower magnifications then it could be several problems, but try to eliminate some of the variables at play. If you can answer some of the above questions for me, I might be able to guide you in a bit better direction.

Good luck!

Since there's only a very small amount of light reaching the lens system of microscopes when on high powers, A special technique (called >>>oil immersion
Not using this technique must be the cause of the problem you are experiencing.
eHow will guide you through the exact procedure of using the oil immersion technique: http://www.ehow.com/how_8431358_focus-high-power-objective-microscope.html
Good luck in exploring the micro world!

This from clinicalmicroscope,com .....

Carl Zeiss is a German brand that is popular for making quality optic lenses. Just like Leica, Zeiss has facilities everywhere in the world. The high end clinical microscopes are made in China and Mexico but Zeiss continues to deal in the United States.
If you had a model number (and year of manufacture) it might be possible to trace, I'm guessing you've not got the original instructions, because it should say there. On a technicality - it doesn't have to say "made in germany" anymore - it would just have markings for Europe.

This is a brand name, not a specific device and model. That said, here is a page describing mode switch in the setup screen using the touch screen for a specific device. I assume a touch screen would have an icon for turning a device off.

The battery is soldered to the CPU. People from Zeiss Germany said that it needs to replace all the CPU. Now a days there is no longer spare parts for that instrument. I recommen you just change the day and time each time you turn it on
