Image processing applications are characterised, among other things, by a specific image scale, which requires a certain distance to the sensor for each lens in the PYRITE, ZIRCONIA and SAPPHIRE series, as these lenses do not have a fixed flange focal distance.

This means that the distance of the lens to the camera varies for each lens with the same magnification. Intermediate rings with lengths from 5 mm to 100 mm and various connections are currently available.
