Camoptic C-Mount Micro-Macro Lens Series
A simple-to-use, compact design lens system delivering up to 27X magnification at a fraction of the price of a stereo microscope or zoom lens system.  The CO1628 lens attaches to any c-mount camera with a sensor of no larger than 1.2" and is usually mounted with the camera onto a long reach or pillar macrostand with lights for viewing subjects such as electronic components, insects, archaeology finds, art restoration projects, plastic or composite materials, welds, drilled holes etc.

The magnification is set by moving the lens towards the subject and refocussing.  There is an iris diaphragm so you can optimise the depth of focus.  This system is quick and simple to use and gives a high quality image with only 0.3% distortion in each axis.
