551 Gehmann rearsight iris with twin polarisers and 1.5x diopter

Incorporates the 550 iris
Iris adjustable over a wide range of 0.5 - 3.0mm
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 - or with one, or both, polarisers
Locking collar allows precise location of the V-mark
Light reflection is kept to a minimum by applying a special matt finish to all external and internal surfaces
Laser engraved indications
Optics 1.5x dioptre with -4.5 to +4.5 dpt correction
Optics can be unscrewed and replaced by the 577-thread adapter to obtain a "classic" iris setup without dioptre adjustment
