Hollow Retroreflector is constructed by three first surface mirrors assembled into a corner cube prism. This produces a lightweight hollow corner cube which is totally insensitive to position and movement. It reflects the incident light back to its original source with good accuracy, regardless of the angle of incidence. Hollow Retroreflector is insensitive to chromatic dispersion of the refractive index of glass and the absorptive of glass, due to the optical path is in air. Hollow Retroreflector is installed in a mount features a variety of mounting holes.
