Corner Cube Prism 20mm AR Coated
CCB-20M
Retro-reflectors, or corner cubes as they are sometimes called, have the property that light incident on the face of the prism is deviated by 180 degrees independently of its angle of incidence. This means that any light incident on the surface will be reflected back along the same path that it came from. These retro-reflectors are extremely precise providing an exact 180 degree deviation within a 5arcsec tolerances. This enables them to be used for high precision applications or with lasers over very long distances. These angle insensitive; mirrors have numerous uses in alignment and metrology. Our retro-reflectors are available uncoated or with a visible broadband AR coating on the face.
◦The corner cube is fabricated under high precision process to assure the reflection of high accuracy light.
◦Light entering the corner cube reflects off each of the three surfaces and the emerging light is parallel to the entrance beam.
◦We also offer CCB-M option with an anti-reflection coating to minimize light power loss.
