HIGH REFLECTIVITY, BROADBAND UV MIRRORS
Nov 1997Newport - New FocusRequest Info
New Focus Inc. says its new mirrors are the first commercially available broadband dielectric mirrors for use in low-power UV and blue lasers such as argon-ion. The Model 51X0 series mirrors offer >99% reflectivity from 300 to 550 nm for any polarization with an angle of incidence from 0° to 45°. The high reflectivity is achieved by stacking two multilayer, high-reflectance coatings centered on adjacent wavelengths. The extremely durable mirrors can be cleaned repeatedly. They are available in 0.5-, 1- and 2-in.-diameter versions with thicknesses of 5, 8 and 12.5 mm, respectively. Surface roughness is <20 Arms.
