PROVIDENCE, R.I., June 24, 2011 — A full line of CO2 laser mirrors and reflectors made from silicon, with or without coatings, and from molybdenum for harsh environments, is available from Laser Research Optics, a division of Meller Optics Inc. The mirrors are offered in silicon for general use, with enhanced copper or DMBR coatings, in uncoated molybdenum for harsh environments, and in copper with gold coatings for high-power applications. Suitable field replacements for use with high- and low-power CO2 lasers, they are supplied in 1- to 3-in.-diameter sizes that are 2 to 10 mm thick, with +0- to −0.005-in. tolerance. Optimized for 10.6 µm at a 45° area of interest, the mirrors meet OEM and ISO-10110 specifications. The silicon mirrors exhibit <2% absorption and scatter losses, and the intrinsically hard molybdenum mirrors achieve >98.1% average reflectance with <1.9% absorption and scatter. Total and phase retardation reflectors are also available. The mirrors are in stock for 24-h delivery.
