20 Most Recent Nikon 7314 Binocular Microscope Questions & Answers

This might be sign of trouble, because the Nylon gears inside might be worn out. I did not noticed a tension ring on Optiphot 1 or 2. The Nikon S and Metaphot from 1960s to 1976 have Nylon gears with tension ring adjustments.

Service Support Nikon Instruments Microscopes and Imaging Systems

My best advice is to contact the support for the instrument. Avoid DIY without expert guidance as the potential for damage to the precision instrument exists which could result in costly repair or replacement.

Sure you did to switch of the power?
Look at the picture.
The change of the lamp is in the manual, but over to many pages, so difficult to make a screenshot, but with the link you can read it yourself:

It might be that Objective lens is not seated properly or very dirty. So perhaps by rotating the objective block may help before trying to clean it. Also try to start with the lowest magnification to see that you have functional microscope before trying higher magnifications. Good luck.

There are a few things that could cause a shadow in the field of view. First if the condenser is not centered, this can create a crescent shaped shadow and rob your image of light. Center the condenser and raise it to within about a 16th of an inch from the top of the stage.
Second, the slider on the head which diverts light from the eyepieces to the camera must be fully engaged to the "camera" position
Third, make sure that the diaphragm on the condenser is not closed too far. There is an adjustment ring for this. Set it to 70-80% of the numerical aperture of the objective you are using.
Fourth: if there is a "swing out" condenser lens you will need it completely in or out depending on the objective you are using. for 2x-5x you need the swing out condenser lens completely out of the light path. For objectives 10x and up you need the swing out condenser lens completely in and centered in the light path.
If these things are properly adjusted you should not have a shadow in the field of view. If you still have a problem, let me know.
