Gehmann 501-A Lens Holder for All Iris Diopters
Gehmann 501-A Universal Lens Holder for Iris Diopters
The Gehmann 501-A lens holder allows a prescription lens to be mounted on the eye side of a rear sight iris. This universal version is designed for iris diopters from other manufacturers and older Gehmann models without a removable front attachment thread.
Universal Compatibility
The Gehmann 501-A features a steel threaded adapter with an M9.5 x 1 connection. It is suitable for Gehmann 510, 510-S and 501MC models, older Gehmann irises and compatible iris diopters from other manufacturers.
Adjustable Lens Holder
The lightweight, pivoting lens holder is made from matt black aluminium and has a diameter of 23 mm. It can be removed from the stainless steel guide rail to make fitting a prescription lens easier. The holder can then be repositioned along the rail and locked in place.
The adapter also provides radial adjustment for precise alignment with the rear sight. The selected position is secured using an Allen screw.
