Corner Cube Retroreflectors

The Corner Cube Retroreflector is composed of three adjacent and perpendicular reflection planes, forming a three-sided cone cube, and the bottom incidence plane is perpendicular to the diagonal of the cone cube. The corner cone cube reflects the incident light at a specific Angle, the incident light Angle does not affect the final light Angle, and the light is reflected at 180°, which provides the best parallelism between the incident beam and the outgoing beam. The processing technology of Tianyanggu corner cone prism is mature, and it is easy to achieve high precision size, and the accuracy of the prism with a size of less than 3 inches can be controlled within 3 ". After milling, fine grinding, grinding and polishing, high precision mirror flatness and Angle accuracy can be achieved.

Features of Corner Cube Retroreflectors

Features of Corner Cube Retroreflectors
  • One-stop customized production: Solar Valley processes various sizes of corner cube retroreflector according to customer requirements.

  • Material: optical glass, fused quartz.

  • Angular cone prism performance: The angular cone cube reflects the incident light at a specific Angle, the incident light Angle does not affect the final light Angle, and the beam is reflected at 180°, which provides the best parallelism between the incident beam and the outgoing beam. Corner prism is often used in laser measurement, positioning and guidance, laser communication, optical transformation, calibration, ranging and so on.

  • Product size indicator description:

    Pyramid prism maximum dimensions: ≤150mm Thickness T≤100mm Surface flatness: incident surface <λ/4@632.8nm reflecting surface <λ/10@632.8nm


  • Surface defect grade: 60-40, 40-20, 20-10 according to customer requirements.

  • Coating: AR, HR metal film, or coating according to customer requirements.
