Re: Selling a BH2 BHT Microscope
Bumping this thread. Also, I am including an Amscope DK-Oil200 Darkfield Condenser for high magnification darkfield with this microscope. Please keep in mind that the condenser will only work up to objectives with NA of 1.1 or less and that immersion darkfield may be variable for those higher NA obj...

Re: Experience with clearance-free Olympus BH2-SRG Rotating Stage Clips.
Just updating this forum post with a question. Does anybody who own the Olympus U-FMP can provide the dimensions of the Allen screw that secures it? I am trying to see if I can mount a U-FMP Mechanical Stage onto a BH2-SRP.

Re: Advice on theorycrafting a Flash Photomicrography setup.
Thank you for the reply @MichaelG. One thing of note is that are there fiber optic cables that take two inputs but only release one? Eg. I can link a fiber optic cable to my background light and a flash unit to one cable?

Re: Is there a doctor in the house?
The second 100x photomicrograph that features a cell almost like an Eosinophil is actually a Neutrophil. That particular slide seems to be a case of Chediak-Higashi. This immunodeficiency impedes the granulation of Neuts preventing adequate respiratory burst used to kill pathogens, mainly bacteria.

I have a question, regarding the how anti-reflection coating and its loss would affect the condenser. Obviously in objectives, the image would lose contrasts due to the scatter. As such, would coating losses in the condenser reduce its NA and potential image quality of the specimen or is that effect...
