This is a Leica MC170HD digital camera. It has a 1/4″, 5 megapixel chip and connects to the computer via a USB 2.0 cable. It also has a 1080p HDMI output port for connection to projectors and such. It threads onto a standard C-type mount, and so can be switched to other microscopes. It has a good frame rate in HDMI and USB modes, so it is good for real-time instruction purposes. The software gives a lot of control over the resulting image.
This is a Javelin Chromachip V camera. Although it has a 1/4″ chip, the output is analog for old-style televisions. It threads onto a standard C-type camera mount and so can be switched to other microscopes. It is light-sensitive and fast, and has good white balance. It can easily be used for real-time instruction. I’m not sure we have any displays that would work with this thing anymore. It was great while the technology lasted.
Instead of a microscope, the cameras can be attached to this nice little f1.4 C-mount lens. This might be useful for photographing larger samples on a copy stand, for example. It can focus from 0.3 m to infinity.
