Various standard lenses having a fixed diaphragm and a fixed focus for different focal lengths f’ = 8 mm, 50 mm and 100 mm are on offer. These lenses are nearly flare-free. They are set and optimised by us for the concrete application. For an integration time of 3 s, the sensitivity of these fast lenses is up to 1cd/m2 accuracy rating.
Furthermore, a focusable lens having a focal length of f’ = 25 mm for a variable object field size/distance is on offer. It is set in the LMK 2000 software using a calibration factor in consideration of the current focus setting. However, further focusable lenses with other focal lengths can be realised and calibrated on request.
