Newport MKS Hollow Metal Retroreflector, Replicated, 12.7 mm, 10 arc sec RBA, Bare Gold 50441-0510AU

The 50441-0510AU low profile replicated hollow metal retroreflector features an outside diameter of 0.5 in. (12.7 mm) and a 10 arc sec return beam accuracy. Our replicated hollow metal retroreflectors are monolithic or single piece construction. Fabricated from a solid piece of Aluminum with a bare gold reflective coating, 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.
