565 Gehmann rearsight iris with 6-colour filter and twin polarisers

Incorporates the patented 510 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.
Removable steel threaded connector for the opportunity to add, for example the 0.0 dioptre.
Light reflection is kept to a minimum by applying a special matt finish to all external and internal surfaces.
Laser engraved indications.
Thread M9.5x1 for all well-known target rifle brands.
