Corner Cube Prisms

Corner cube prisms are able to reflect an incoming beam of light by 180° regardless of the angle of incidence. The prism is made up of three roof surfaces and one flat circular hypotenuse surface.  Corner cube prisms are used for beam steering and surveying applications. Other applications relating to corner cubes are rail and tunnel surveying, building and construction surveying, enviromental and structual monitoring, mining conditions monitoring, geospacial engineering.

Knight Optical supply a range of custom high-precision retro-reflectors offering excellent parallelism between the incoming and exiting beams.  We are able to make custom corner cube retro reflector prisms in all types of materials and to any sized aperture to create your unique custom corner cube. We can supply the prisms mounted and unmounted for seamless integration into your application.  Our custom mounted type is housed in a metal holder with an L-bracket for fixed installations, enabling the prism to be fixed to a wall for distance measurements.

Knight Optical supply high quality custom mounted corner cube prisms made to your exact specification.  Every component is individually tested by our highly skilled technicians in our state of art metrology lab to ensure all components meet our high quality standards.  All prisms are tested on our Trioptics Prism Master capable of accuracy to 3 arc seconds.
