Hollow Metal Retroreflector, Replicated, 25.4 mm, 2 arc sec RBA, Al-MgF2

The 50441-1002AL low profile replicated hollow metal retroreflector features an outside diameter of 1.0 in. (25.4 mm) and a 2 arc sec return beam accuracy. Our replicated hollow metal retroreflectors are monolithic or single piece construction. Fabricated from a solid piece of Aluminum with an Al-MgF₂ 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.
