Help with a crooked fine focus knob

I have bought an Olympus BH2-BHT Microscope a while back and found that the right focus knob is misaligned relative to the drive shaft. This leads to a crooked fine focus knob which may or may not function properly. Does anybody know if its possible to straighten the focus knob and align it back to ...

Thoughts on a reducing relay and a higher mag photoeyepiece

Hello, I am interested in using a higher magnification Olympus NFK 3.3 eyepiece and a reducing relay to mimic the image of a NFK 2.5 eyepiece or even a 1.67x. Does anybody have experience in doing such an optical setup where a higher mag photoeyepiece is coupled with a relay to increase F.O.V ? If s...

Re: Dovetail Condenser Adapter for Olympus BH2

Update: I have made a circular condenser adapter that fits 37mm condensers. This dovetail attachment allows me to use an Abbe condenser and mount it under my BH2. The only caveat is that a temporary disassembly of the stage as well as nosepiece is required to allow for attachment. Despite its somewh...

Re: Dovetail Condenser Adapter for Olympus BH2

The main thing that I am trying to look for is a dovetail mount that when attached can turn a circular mounted condenser into a compatible dovetail. The particular example I am looking for is seen in gekko's post where he modifies a condenser to fit into the mount.

Dovetail Condenser Adapter for Olympus BH2

I have just recently acquired an Olympus BHT-BH2 Microscope but the lack of a filter holder has really irked me. Making a styrofoam base that elevates filters is still not satisfactory in my eyes. I am unable to perform Rheinberg Illumation or higher darkfield from the 10x to 20x S Plan Objectives. ...

Resale Value of a used BH2 Trinocular Microscope

Hello, I was wondering the potential resale value of a used Olympus BH2-BHT Trinocular Microscope with 5 objectives, 2 being an SPlan 40x 0.70 and SPlan 100x 1.25. The condenser is a fliptop 0.16-0.90NA condenser.

Crystals

When I make crystals for observation I usually add the solute in a water/alcohol solution and let evaporation takes it course. My question is when crystals are made this way do I have to cover it with a coverslip to preserve it or can I leave it out in the air after evaporation is done?

My microscope is a no name without a field diaphragm or collector lens so Kohler is impossible? Would anyone inquire other methods of reducing uneven illumination when taking pictures? I was thinking of using a ground glass diffuser but I'm not sure about other approaches.

I'll take pictures once I get back home but the main issue is that a dovetail piece that connects the main focus rack and pinion to the fine focus mechanism keeps detaching in my LOMO.

Re: Fitting a Lomo 1.4 Aplanatic condenser to my microscope.

zzffnn, my preposition is to make a threaded ring that raises the top lens to a much more reachable height. It'll fit between where you would normally put the top lens and acts as a height increaser.
