New Optics For The Lab
I've got a Svbony SV205 "8Mpixel" imager. It's a YUV USB3.0 device so it plugs in to Linux and just works. Unfortunately it didn't plug straight in to the Kronus trinocular microscope, but a few hours later I'd modelled an adapter that I'm almost happy with. The plastic shell wasn't sufficiently lightproof though, so I added some aluminium tape (which, yes, I will test as a slide touch plate at some point).
Notice how the USB lead wants to pass between your eyeballs when the imager is in the correct orientation.
I've not played much with the lighting and so forth yet, but I took this screenshot of the calibration slide while fiddling around. The squares are 50μm and the linear divisions are 10μm. Looks like I may have a bit of tilt in my adaptor as the left side is a bit out of focus. Unlike the phone camera there is no clever filtering and pixel-guessing going on, so it looks a little drab.
