Hollow Retroreflectors

Spectrum Scientific’s hollow retroreflectors (HR) have a rugged, one piece construction and are manufactured from solid aluminum making them insensitive to vibration, position and movement and ideal for use in Michelson type interferometers, FTIR spectrometers and laser based tracking systems.

Key advantages of our our hollow retroreflectors include:

  • Ability to incorporate mounting features and fiducials onto the retroreflector itself for easy alignment giving additional design and cost benefits
  • Return beam accuracy < 2 arcsec
  • Gold or Aluminum coating (bare metal or with protective overcoat)
