with integrated Gehmann polarising filters
- by swinging in a polarising filter into which special quartz crystals are embedded,
  the so-called reflected rays are eliminated
- by engaging the second polarising filter, the position of the quartz crystals relative to each other can be changed
  so that they achieve a 10 to 90% stepless light absorption (varied brightness)
all colour and polarising filters can be used independently or combined
open aiming also possible without colour and polarising filters
