Using a video camera as a microscope

English

Some cheap computer video cameras have adjustable focus lenses that can focus almost right up to the lens. This allows you to aim the camera straight up, and put a microscope slide on the lens ring, and focus on the slide.

Shown below is a Logitech QuickCam camera, facing up, with the microscope slide on top of the lens ring. The video shows the procedure, with a voice-over from the author (me! Hi there!).
