Corner Cube Retroreflectors

Standard corner cubes with sub arc second beam deviation over the full diameter of the clear aperture. Down to 3 arcsecond beam deviation.
Protected metal coatings to reduce phase shifting wavefront aberrations and sharp roof edges, are available upon request. Also available mounted.
Truncated retroreflectors for light-weighting applications and spatial constraints.
Precise beam deviation, transmitted wavefront, and positioning of the theoretical apex to datum surfaces.

Product Details

A corner cube (or cube corner), also known as a retroreflector, is an optical component with the unique ability to return an incoming beam of light directly towards its point of origin regardless of the beam's angle of entry. This property makes this prism type ideal for a wide variety of applications, such as laser resonator cavities, land surveying, ground based range-finding, satellite communications and space vehicle docking.

Wisoptic offer a wide variety of retroreflectors at competitive prices and lead times, and are able to accommodate the most demanding requirements. Custom laser-line and broadband anti-reflection coatings are available on the entry faces; and protected aluminium, silver, or gold coatings are available on the reflecting faces to enhance total internal reflection.
