Re: Darkfield Adapter for Whole Slide Imaging

I liked the result, next step is to place more LEDs around the perimeter, in order to have more light control. Anybody tried this type of illumination already ? To my shame, Saul, I still have not summoned-up the courage try mounting some tiny ‘surface-mount’ LEDs that I bought last year. Ordered 0...

Re: Half-mirror

I'm assuming that's a resin printed dovetailed cube. I don't know where it goes, but could you fit a 20mm 50/50 non-polarizing beam splitter cube in there? Then you could get one of these to experiment with for $22: https://www.ebay.com/itm/Cube-Beam-Splitter-Prism-Ratio-Optical-Glass-50-50-Spectro...

Half-mirror

Looking for the half-mirror (not dichroic) for the Nikon BF/DF DIY cube.

Proof of the concept was made with the SurplusShed dichroic mirror (at the left),working model is at the right, used half-mirror leftover piece.
