Product Family Description

  • Incident Light is Reflected Back to the Source
  • Down to 3 Arcsecond Beam Deviation
  • Useful for Surveying and Alignment
  • Also Available Mounted

TECHSPEC® N-BK7 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 do that only at the normal incidence. As a result, corner cube retroreflectors are useful where precision alignment is impossible or time-consuming. TECHSPEC® N-BK7 Corner Cube Retroreflectors are available with the dihedral surfaces either uncoated or coated with silver. The silver coating provides a larger acceptance angle while the uncoated option, which relies on total internal reflection, provides optimum reflectivity. This coating is covered by a protective black overpaint. Please note, this protective coat increases the diameter of the corner cube retroreflector by 30-60 µm. The input face is available uncoated or coated with an antireflection coating optimized for either visible wavelengths or near infrared wavelengths, including 1064nm and 1550nm.
