Re: How to Diy objective parcentering.

About a year ago, I sold all fixed nose wheels and switched to using two phase nose wheels.

Before that, I would like to emphasize again that I will not have a conclusion and accept any comments. All I can do is be honest.

Re: WTB: Olympus BH2-AN Analyser for DIC

I admit it is difficult to make comparisons and draw conclusions, but coincidentally, I have both AH and BH2 DIC kits and have obtained test images of both. If anyone is interested, I can publish them.

The analyzer (polarizer) in b2-na cannot be disassembled and is attached to the top cover of the prism slider box in an inclined manner. I didn't even know it had a separate number.

older Olympus NIC condenser from the Vanox-BH

Coincidentally, I happen to have both the Vanox AH and BH2 DIC kits at the same time. It is safe to say that their top lens components are fully compatible and do not require any modifications.
