Super Mirrors

Super Mirrors

OptoSigma's Super Mirror family are a group of mirrors with extremely high reflectivities. These mirrors are ideal for Fabry-Perot resonator cavities where high finnesse and narrow spectral bandwiths are required. We employ highly specialized polishing techniques that enable low scatter based upon surface roughness of Ra<0.1nm and we also utilize Ion-Beam Sputtering (IBS) optical coating processes. Our standard products are for 1064nm (R>99.999%) and 532nm (R>99.9995%). Custom wavelengths and or sizes available upon request.
