Superpolished Mirrors
Sep 1, 2011 — REO’s new superpolished laser mirrors offer low loss and can be produced on a number of substrate materials. Their microroughness is <0.5 Å, enabling scattering loss of <5 ppm and finesse of 200,000 when incorporated into optical cavities. Ion beam-sputtered coatings, used to take advantage of the ultrasmooth surfaces, deliver reflectivities of >99.998% at any wavelength in the 450-nm to 2-μm range. The mirrors are supplied with diameters in the 6- to 101-mm range, with...
