Hollow Retroreflectors

Hollow Retroreflectors

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


Spectrum Scientific offers a range of standard mirrors. If we do not have a mirror that meets your requirement, please contact our sales department as new mirrors are manufactured on a regular basis.
