Corner Cube Retroreflectors

  • Introduction

Corner Cube Retroreflectors


Corner cube is total reflecting prism formed by 3 perpendicular surfaces, where the incident light angle does not influence the final emerging light angle but reflected by 180°, it offers excellent parallelism between the incident and exit beams.


Hyperion Optics supplies both corner cube in mount or without mount, our precision corner cube retroreflectors have been used for Laser ranging, positioning and guidance, laser communication, optical transformation.


Our typical production accuracy is beam deviation < 5 arc sec in diameter within 2 inches. Please see our precision and tolerance grid for your information.
