Question about Science & Laboratory
I have a Carlsan single occular compound microscope. The course and fine adjustment knobs raise or lower the stage to focus. Lately once I have my slide in focus and I let go of the adjustment knob the stage level begins to slowly decend thus unfocusing the image. As this is happening I can see the course adjustment knob slowly spin. The ends of the fine adjustment knobs have heads that look like they could be adjusted with a flathead screwdriver but the ends of the course adjustment knobs have no such head. It seems like I need to get some more tension between the knobs and the track that they move on. I appreciate any help.
Try holding the Right knob so it does not move, whilst firmly moving the Left knob towards you (clockwise), this is the adjusting method used on Zeiss Jena 1960's High End microscopes, e.g Eduaval & Ergaval.
