Replicated Hollow Metal Retroreflectors
  • Monolithic, all metal construction
  • Integral mount
  • Multiple return beam accuracy options
  • Rugged, impact resistant construction

Product Description

Hollow roof prisms and retroreflectors are typically used in cases where the optical path through a glass prism would be undesirable, where weight must be reduced, where the element must be used in environments with high shock and vibration levels, or where the element must be thermally stable in its mount.

The majority of the hollow metal retroreflectors that we produce are designed and manufactured to custom specifications for a wide variety of OEM applications such as FTIR Instrumentation and Laser Coordinate Measuring. Our custom retroreflectors are typically manufactured using either a stainless-steel or Aluminum substrate with either a Bare Gold, Bare Aluminum, or Protected Aluminum coating. Substrate sizes range from 3 mm to 65 mm in virtually any shape that can be machined or molded.

Catalog Hollow Metal Retroreflectors

Our replicated hollow metal retroreflectors are monolithic or single piece construction. Fabricated from a solid piece of Aluminum, the facets of the mirror cannot shift and return beam accuracy is unaffected by vibration. Using front-surface reflection, the mirrors are achromatic and require no wavelength-dependent refraction offset. We offer 4 standard sizes of high-precision cylindrical retroreflectors, each with 3 different high-precision return beam accuracies. We also offer a 2.5" hexagonal shaped retroreflectors with 4 different return beam accuracies ranging from 30 arc sec. return beam accuracy for applications that do not require high precision to 5 arc sec. for high precision applications. The mirrors are coated with bare Gold, which provides very high reflectance from the near infrared through long wave infrared.
