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, retroreflector with 30 arc sec. return beam accuracy for applications that do not require the precision of our …
