C-Mount Adapters are used by most dedicated microscopy cameras.  C-Mounts have a 1" diameter thread and typically are available in magnification factors matching the camera sensor sizes of 1", 2/3" or 1/2", and sometimes 1/3".  For instance, a camera with a 1/2" diagonal CCD sensor will best match a 0.5x C-mount adapter.  This will provide the largest rectangular field of view (FOV) without vignetting.
