Well done!

How did you illuminate?
Thanks! Illumination is done through the objective with a 395nm LED installed in place of standard halogen lamp, yellow blocking filter included in ОИ-28 set is used to cut off reflected blue spectrum.

Totally crazy that no-one has bought this from you!
It also was in eBay for some time and had like 3 watching and one (denied) 70$ offer. I really hope it was a joke.

Re: LOMO MƂP-1 stand problem

Hi, have you tried to rotate coarse focus knobs in opposite directions? IIRC it is the way to tight/loose macro focusing on those models.

Re: looking for a plan 2.5x objective

Also it indeed needs plan compensating eyepieces (PK as Zeiss called them at the time). Are you sure about the "K" for correction? Many lower power Zeiss Jena objectives were not calculated to be used with correcting eyepieces. I don't know this objective. Yes, I am sure about the correction. Polmi...

Re: looking for a plan 2.5x objective

Hello! The mentioned CZJ Plan 2,5 is designed for 20 mm FOV I believe, it's from Polmi A microscope which was equipped with 10x/20 eyepiece from the factory. I'm really lucky to have one =)

I looked up the formula and each pill appears to have 130 mg of lactose monohydrate among other things. Maybe it is giving such nice visuals. I think I had pure lactose somewhere, maybe will try to prepare some crystals of it later.

Storms of a wounded mind

Have you ever wondered how antipsychotic drug crystals look under the polarizing microscope? Well, I certainly have, and luckily I had some spare Rispolept tablets left since I was prescribed to take them for some time. And since I have finally repaired my pol microscope, I decided to give it a try....

Re: Looking for second hand phase contrast systems-

I have a Zeiss Jena Nf with Phv variable (two rings) phase contrast system for pancratic condenser and plan achromatic objectives and I really love it. I will post some photos when I'll have more time. Unfortunately CZJ microscopes and accessories are rather rare outside of Germany and former Soviet...
