If you have a rotating perforated diaphragm, that means the hole you want to use is blocking the light partially. Make sure your diaphragm is set correctly.

Also, you might want to check that your objective is set and aligned, that could also cause half the field being dark.

Did you move the brighness control. It is on the right side of the equipment. If not, it could be the video board inside of the equipment

Why does my zeiss humphrey visual field machine keep shutting down?


Sounds like a heat, thermal issue. You may have a non- functioning cooling fan somewhere inside. There are several of them so don't be fooled if you hear one of them running. Same issue happens with CPUs on PC computers. Will suddenly shut off if too hot.

Zeiss humphrey system startup state 19


I believe "state 19" is a weak main illumination bulb. Not sure if it's the same on your 740, but that's what the problem was with our 750i. Even though the bulb appears to be working, they dim over time and won't pass the start up calibration checks. On ours, there is a round access panel on top of the unit to service this bulb. Just be careful removing the bulb and don't bump any of the clear optical wheels. Part # 2660021106082 (for 750i. not sure about 740) Call Zeiss to confirm. Realize this is an old post so info is for future readers.

How do I increase the field of view on a zeiss OpMi-1?


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.

How to troubleshoot a microscope having uneven brightness in the observation field?


uneveness of of brightness in the optical field of view (FOV) can be caused by a number of variables, but often times is do to miss alignment of the condenser. Typically when this is the problem there the "hot" (brightess area) will be shifted to one corner or another in the FOV. There are usually some sort of adjustment screw underneath the stage that will allow you to do the alignment. It is easiest if you close down the iris on condenser and adjust the height of the condenser until you can see an octagonal shape appear, then center it in the FOV.

If the uneveness is equally the same throughout the FOV then it may have to do with the position or the height of the condenser. Generally speaking the lower the magnification, the further the condenser should be away from the slide. The condenser narrows or broadens the light allowing you to fill the entire FOV of the objective.

Depending on the quality and the level of the microscope though, you may find that no matter what you do at lower magnifications you can do very little to improve this. I see this a lot with LED models. The dispersion pattern of an LED is much more focused then a halogen, which is GREAT for higher magnification, but often times manufactures will upgrade from halogen to LED an never change the optics of th collector lens and condenser to flatten out the illumination better.

Parfocal microscope


Are you able to focus on the specimen? Is the problem the same if you switch to a higher magnification lens?
Could be several things, a slider half way in, a turret not clicked in to the notch, ie condenser, a filter partway in.

Microscopy; Relatively large spots on unknown surface obstructing view


HELLO..

There is five part in microscope

1. Eye piece

2. Binocular tube

3.Objective

4. magnification changer or joom accembaley

5. illumination segment

Try to make it out which part is gives a effect to your vision.

as per my suggesition illumination asembely you just clean it first.

keep in touch
