This is the rig I use to take all photomicrographs. At the top, actually recording the images. is a Canon 5D MkII DSLR. The DSLR sits on the 3rd port of a stereo research-grade microscope. For additional lighting (when needed) you can see a pair of optical light pipes coming forward from the black PSU sitting just behind the microscope.
You might notice that there are no bellows in the camera optical path. Bellows are often used to make the camera parfocal with the microscope, so that if you look through the microscope eyepieces and the subject is in focus, then it is automatically in focus on the camera as well. Personally I don’t like that way of operating the kit. Instead I use the microscope to position the subject, and then looking at the camera’s LCD screen I carefully focus the subject. In that way you can be sure that any image captured by the camera will be in good focus, and you don’t have to be continually checking that your parfocality is spot on every time you use the kit.
