The hollow retroreflector (also known as hollow corner cube or backward reflector) is a key component in delay lines, functioning to return laser beams parallelly without being affected by whether the incident angle is precisely perpendicular. The hollow corner cube reflector has a robust structure, being a monolithic design made of solid aluminum, and is insensitive to vibration, position, and movement, making it highly suitable for use in Michelson interferometers, FTIR spectrometers, and laser tracking systems. Generally, there are two types: glass-fused hollow retroreflectors and metal-integrated hollow retroreflectors.
