Product Family Description

  • Incident Light is Reflected Back to the Source
  • Useful for Surveying and Alignment
  • ¼-20 Tapped Holes for Easy Mounting
  • Also Available Unmounted

Due to their complex shape, corner cube retroreflectors can often be difficult to mount. Our TECHSPEC® Mounted N-BK7 Corner Cube Retroreflectors provide a convenient and durable solution. Mounted in an aluminum body and held in place with RTV potting cement, our TECHSPEC® Mounted N-BK7 Corner Cube Retroreflectors are easily integrated via two ¼-20 tapped holes. In addition, each retroreflector has silvered reflecting surfaces to decrease polarization effects and increase field of view.

Corner cube retroreflectors are designed to reflect any ray or beam entering the prism face, regardless of the orientation of the prism, back onto itself. A mirror will only do that at the normal angle of incidence. As a result, corner cube retroreflectors are ideal where precision alignment is difficult or time-consuming. They feature three total internal reflections and will function even at very large angles of incidence.
