Why is the field of view vignetted or too dark on my Nikon Microscope?
- RRichard CollinsAug 18, 2025
There are several reasons why the field of view might be vignetted or too dark. It could be due to incorrect installation, an improperly adjusted optical path selector lever, the nosepiece not being in the clickstop position, dirty lenses or specimen, the aperture diaphragm opening being too small, or an unnecessary filter being in the optical path. Check these potential causes and make the appropriate adjustments.
