Test & Measurement White Papers
Monolithic Hollow Corner Cube Retroreflectors for Precision Metrology
This white paper compares the advantages and disadvantages of different types of retroreflectors. It highlights the advantages of monolithic, hollow retroreflectors which do not suffer from chromatic aberration making them ideal for use with broadband or multiple frequency light sources. Manufactured from a solid block of aluminum they also offer high accuracy and repeatability and are thermally stable, insensitive to vibration, position and movement.
