Hollow Metal Retroreflector, Replicated, 63.5 mm OD, 30 arc sec RBA
Model: 50394-2530
Product Series Overview
Replicated Hollow Metal RetroreflectorsThe 50394-2530 is a Replicated Hollow Metal Retroreflector with an outside diameter of 63.5 mm and a 30 arc sec Return Beam Accuracy. 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. The mirrors are coated with bare Gold, which provides very high reflectance from the near infrared through long wave infrared.
Stable Monolithic Construction
Gold Coating with High IR Reflectivity
Advantages vs. Glass Retro Reflectors
Unlike solid glass retroreflectors, the optical path is entirely in air so efficient performance is obtained without antireflection coatings which limit the operating wavelength range. Using a novel patented fabrication technique, return beam accuracy as low as 2 arc sec. is economically achieved. These retroreflectors are offered in 12.7, 19.1, 25.4, 38.1, or 63.5 mm diameter and 30, 10, 5, or 2 arc sec return beam accuracy.
