575-0 Gehmann rearsight iris with 6-colour filter, twin polariser and diopter 0.0x

575-0 Gehmann rearsight iris with 6-colour filter, twin polariser and diopter 0.0x

Incorporates the patented 565 iris
Iris adjustable over a wide range of 0.5 – 3.0mm
6 optically flat glass colour filters which can be precisely located in position: Yellow, Light Green, Orange, Purple, Dark Grey and Light Grey
Two separately adjustable polarisation filters
Our Gehmann polarization filters offer two key advantages that lead to noticeably better and longer-lasting performance of the aiming eye. Light oscillations (“flicker”) can be filtered so that only specific oscillation directions pass through the polarizing filter
By engaging a polarizing filter in which special quartz crystals are embedded, the so-called reflex rays are eliminated
By switching on the second polarizing filter, the position of the quartz crystals relative to each other can be changed so that they achieve a 10 to 90%, continuous, light absorption (changed brightness)
Can be used as an iris only
Locking collar allows precise location of the V-mark
All colour and polarizing filters can be used separately or combined
Light reflection is kept to a minimum by applying a special matt finish to all external and internal surfaces
