Product description

GMH20 hollow corner-cube retroreflectors use three mutually perpendicular reflective faces in a trihedral arrangement. The category describes a 180° return direction that is independent of the incoming beam angle.

The three listed models specify K9 material, a 23 mm clear aperture and an SM05 threaded mounting adapter. Choose among the model-listed protected UV-reflective aluminum, protected silver and protected gold coatings.

The source describes an open optical path intended to avoid dispersion, chromatic effects, material absorption and front-surface reflection associated with a solid glass prism. The three coating choices are identified on the individual model records.
