Retro-reflectors

Retro-reflector produces three total internal reflection. A beam is reflected back and parallel to the original beam. The image is inverted and reversed. It is commonly applied for optical signaling, laser interferometry and a variety of distance and time measurements. Standard and broadband antireflection coatings are available upon request, see our standard optics components below.
