Lenses
To achieve the optimum image display size on the monitor, the lens must be selected to suit the camera chip
and the diameter of the endoscope.
You will find different lenses on the following page.
Example:
An endoscope with a 2.8 mm diameter is used in conjunction with a USB camera containing a 1/3
camera chip. We recommend using a 25 mm lens to get a full-size image.
