hi again,i was told that Olympus manufactures seam to be a little reluctant to help in matters unless you buy a years subscription fee on repair for your microscope is this the case.would a certain library hold this booklet or museum.

hi mitch,thank for advice on khs microscope,i have looked befor at that sight ,maybe it the booklet that would of come with the microscope at that time,if different from manual,thank again.

Dave, I never tried darkfield at anything above 10x. I didn't really like the effect myself. Are you adjusting the condenser up or down? I think you have to fine tune darkfield by raising or lowering the whole condenser with the knob under the stage.

Other than that, I don't really have any experience with it.

Mitch, I bought an Amscope darkfield from you in Jan. I'm having problems with getting darkfield using 100x objective and have tried every trick I know. Can you help me? Were you able to view in dark field with 100x? I got oil immersion condensor, new objective, thin slides and slide covers, special oils, etc. NO luck. Need help.
