Optics with Superpolished Surfaces < 1 Å RM

Oct. 27, 2010 - PRLog -- Plano substrates of up to 3" diameter can be polished to better than λ/10 surface flatness with 10-5 surface quality and surface roughness of less than 1 angstrom RMS.
Super-polished or laser quality polished substrates and assemblies are ideal for use as low-loss laser mirrors, high energy waveguides and in cavity ring-down spectroscopy (CRDS) where thermal stability, surface scatter and high laser damage thresholds are key requirements. We can also provide ion-beam-sputtered (IBS) anti-reflection, beam splitter and high-reflection coatings on these and other materials at wavelengths from 266 nm to > 3 μm.
