A diopter correction WITHOUT magnification!
The target picture size remains equal and clear throughout the entire dioptric adjustment range of +/- 5 dpt. Using a highly refractive type of glass makes it possible to correct spherical defective vision without having any optical magnification. Shooting lenses are at a natural disadvantage to the diopter 0.0x. This is because a shooting lens is made to correct visual defects at the time the shooter is tested. Throughout the day, dependant on sugar and fatigue levels, the eyesight can change rendering the lens inefficient. The advantage compared to usual shooters‘ frames is the possibility to correct the spherical defect through slight fine adjustments any time, while neglecting the need of time-consuming shooting frame setups. According to DSB rules approved without restriction for DSB (German Shooting Sports Federation) and finally approved by ISSF!
The Gehmann 530-0 is a high-performance rear sight iris engineered for precision target shooting. Featuring Gehmann's patented adjustable iris mechanism and advanced 0.0x corrective optics, it delivers exceptional durability, accuracy and repeatability without image magnification, making it an ideal choice for competitive shooters.
Its compact design incorporates an adjustable iris with a 0.5mm to 3.0mm aperture range, allowing precise control of depth of field and sight clarity across a wide variety of lighting conditions.
Unlike conventional iris designs, the fixed-seat iris uses individually located hardened spring steel blades. A unique aperture control system applies pressure through a precision steel tube to the central aiming ring, ensuring the aperture remains a perfect circle throughout its adjustment range. This innovative design maintains the exact aiming point regardless of aperture size.
Constructed from hardened spring steel rather than brass, the iris is exceptionally robust and suitable for use with both small and large calibre target rifles. Because the iris blades are permanently connected to the main body, there is no possibility of point-of-impact shift during adjustment, providing complete confidence in shot-to-shot consistency.
The integrated 0.0x optical system provides no image magnification, while offering an adjustable -5.0 to +5.0 dioptre correction to compensate for individual eyesight requirements. The optical assembly can also be removed and replaced with the Gehmann 577 thread adapter to create a traditional iris configuration without dioptre adjustment.
Protected by Gehmann patents and finished in a distinctive black and red colour scheme, the 530-0 is fully approved for competition under both ISSF and DSB regulations.
Combining outstanding mechanical precision with advanced optical correction, the Gehmann 530-0 offers serious target shooters a reliable, competition-ready rear sight iris designed to deliver exceptional accuracy, durability and a consistently clear sight picture.
Enhance your sight picture and reduce eye fatigue with this premium Gehmann adjustable iris, designed for target rifle shooters who demand maximum optical performance and precision.
Featuring the renowned Gehmann 550 iris, this unit offers a continuously adjustable aperture from 0.5mm to 3.0mm, allowing you to optimise your sight picture for varying lighting conditions and target contrasts.
The integrated dual polarising filter system provides exceptional control over light transmission and glare:
First polarising filter reduces distracting light flicker by filtering specific light oscillations, helping to create a clearer, more comfortable sight picture.
Second adjustable polarising filter works in conjunction with the first to provide continuously variable light absorption from 10% to 90%, allowing precise brightness adjustment to suit changing conditions.
The filters can be used independently or together, giving you complete flexibility. The unit can also be used as a standard adjustable iris without engaging either polariser. Ideal for competitive target rifle shooters seeking superior control over aperture size, brightness, glare reduction and eyesight correction in one precision-engineered sighting accessory.
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
Gehmann patented, so not available from any other manufacturers
Laser engraved indications
Optics 0.0x WITHOUT magnification, dioptre adjustment from -5.0 to +5.0 dpt.
According to DSB-SpO, fully approved for all competition classes and now internationally approved by ISSF
Finished in an easily identifiable black and red finish
Optics can be unscrewed and replaced by the 577-thread adapter to obtain a "classic" iris setup without dioptre adjustment
Thread M9.5x1 for all well-known target rifle brands
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.
