The 50394-2520 is a Replicated Hollow Metal Retroreflector with an outside diameter of 63.5 mm and a 20 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. We offer 4 standard sizes of high-precision cylindrical retroreflectors, each with 3 different high-precision return beam accuracies. We also offer 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 higher precision applications.The mirrors are coated with bare Gold, which provides very high reflectance from the near infrared through long wave infrared.
