Corner Cube Prisms/ Corner Cube Retroreflectors

Feature: 
Incident light deviates by **0 deg independently of the angle of incidence

Applications: 
Plumb Level, Surveying, Alignment, Range finding, Laser range finder, Optical Tooling, Distance finding, Distance measurement, Optical signal dispose, Optical signal process, Laser interferometer, Fire detector, etc..

Description:
BK7 or UVFS Corner cube retroreflectors are designed to deviate incident light by **0 degrees independent of the angle of incidence. These prisms have 3 mirror surfaces making angles of *0 degrees to each other, juxtaposed to form the corner of a cube with the entrance face perpendicular to cube diagonal. All beams, independent of the direction of incidence, are reflected back. Corner cubes are used for high precision applications or with lasers working in very long distances.

The corner cube can reflect the incident light back its original source. It is used in length measurement system as its reflector. It has been designed for measuring the distance between the moon and the earth, when Apollo spaceship reached the moon, corner cube was set on the surface of the moon for scientific research use.

Retroreflection Prisms are used in applications where precision alignment is difficult or tedious. Retroflection Prisms reflect incident light back to the light source no matter the orientation of the Retroreflection Prism. Unlike an Optical Mirror, which needs to be at the normal angle of incidence in order to reflect light back to the source, a Retroreflection Prism can be oriented in any position so long as the light is hitting the entrance face. A Retroreflection Prism utilizes several total internal reflections to enable it to operate at even the most extreme angles of incidence.
