Our custom etched reticles are manufactured to go into many commercial 12x – 45x sporting scopes. At that magnification, these reticles have to be free of defects to provide a clear line of sight and pinpoint alignment. Our premier etched reticles reach line-widths down to 3 microns, Scratch Dig < 10/2 with AR coatings of R <1.5% while our gratings can reach down to 160nm.
Patterns vary from simple cross hairs and standard resolution targets to sophisticated sighting reticles and registration patterns for commercial, military or aerospace applications. Most of our illuminated reticles today are etched with common substrate materials being soda-lime float glass, borosilicate crown glass, quartz and fused silica.
AgniRoth OPTIK graticules come with chrome structures, diffractive gratings or etched and filled luminous structures.
