575-579-0 Gehmann rearsight iris with 6-colour filter, twin polariser, 0.0x diopter and cylindrical

Designed for the serious competition shooter, this premium Gehmann rear sight iris combines advanced optical technology with unrivalled adjustability. Featuring the patented Gehmann 565 iris, integrated colour filters, twin polarising filters and innovative corrective optics, it provides a highly customisable sight picture while allowing shooters to compensate for diagnosed vision imperfections.

The patented Gehmann 565 iris offers a continuously adjustable aperture from 0.5mm to 3.0mm, enabling precise control of depth of field and target clarity in changing lighting conditions.

The integrated six-position colour filter system incorporates precision optically flat glass filters that can be accurately selected to enhance contrast and improve target definition. Filter colours include:

• Yellow
• Light Green
• Orange
• Purple
• Dark Grey
• Light Grey

The dual independently adjustable polarising filters provide exceptional control over glare and brightness:

• The first polarising filter reduces distracting light flicker by filtering unwanted light oscillations, helping to reduce eye fatigue.
• An integrated quartz crystal polariser eliminates unwanted reflected light (reflex rays) for a sharper, cleaner sight picture.
• The second polarising filter works in conjunction with the first to provide continuously adjustable light absorption from 10% to 90%, allowing brightness to be fine-tuned for virtually any lighting condition.

All colour and polarising filters can be used independently or combined to create the optimum viewing conditions. The unit may also be used as a standard adjustable iris without engaging any filters.

A standout feature of this model is its revolutionary corrective optics, specifically designed to compensate for diagnosed axial and spherical vision errors, helping shooters achieve a clearer and more precisely focused sight picture. The optical system provides 0.0x magnification (no image enlargement) with an impressive -5.0 to +5.0 dioptre adjustment, making it suitable for a wide range of eyesight corrections.

The innovative corrective optical system is exclusive to Gehmann and is protected by patent, making it unavailable from any other manufacturer. The sight is fully approved for competition under ISSF and DSB regulations.

Developed for elite target shooters who demand the highest level of optical performance, this Gehmann rear sight iris offers outstanding control over aperture size, colour filtering, glare reduction and eyesight correction, helping you achieve the clearest possible sight picture and maximum shooting precision.
