Hollow Retroreflectors

Hollow Retroreflectors

Spectrum Scientific’s hollow retroreflectors (HR) have a rugged, one-piece construction made from solid aluminum, making them insensitive to vibration, position and movement. They are ideally suited for Michelson type interferometers, FTIR spectrometers and laser based tracking systems. Our standard HR coatings include aluminum and gold, in both bare metal form and with protective overcoats. We also offer custom mounting features directly incorporated onto the retroreflectors.


In addition to custom manufactured retroreflectors, Spectrum Scientific offers a range of standard retroreflectors. If we do not have a retroreflector that meets your requirement, please contact our sales department as new retroreflectors are manufactured on a regular basis.
