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 50326 series retroreflectors. The mirrors are coated with bare Gold, which provides very high reflectance from the near infrared through long wave infrared.
