Ultra smooth and ultra-high (reflectivity>99.995%) reflectivity mirror flat/concave mirror

Ring laser gyroscope components or so-called super mirrors in certain scientific applications require coated optical elements with extremely low losses (i.e. absorption and scattering). These mirrors also have Max with R>99.998% and total loss<10 ppm Reflectance Xiaoxiao uses an improved IBS machine from Germany to produce coatings on ultra polished substrates. The cleanliness of the machine and environment is maintained in a dedicated ultra clean room, where extensive substrate pretreatment and post-treatment are carried out. The measuring devices used for program inspection, such as white light profilometers and high-resolution microscopes (up to x 1000), are already in place. The customized cavity decay setting allows for the determination of reflection and reference loss with up to four decimal places of accuracy.
