Optical corner cube retroreflectors are comprised of three reflecting surfaces, which are perpendicular to each other. Corner cube reflector can return an incident light beam in the original direction whatever the incident direction it is. It offers excellent parallelism of incoming and reflecting beams. It is usually directed to be applied in angular deviation,and also commonly used in the fields of surveying and laser ranging .
Hangzhou Shalom EO offers corner cube retroreflectors made from BK7.
