The Fabry-Perot type resonator cavity is often used for measuring extremely high accuracy time or distance with use of the light. Super mirror is a ultra-high performance mirror that surface reflectance is close to 1 (100%) as much as possible in order to increase the performance of the resonator.

◦By using an ion beam sputtering (IBS), high quality and dense coating with few defects has been coated.
◦With a special polishing technique, the low-scattering substrate of surface flatness Ra<0.1nm is used.
◦The mirror coating with reflectivity of 99.999% is achieved from the coating design technology that had been developed for many years.
◦Scattering loss due to the substrate and the coating is very small, when it is incorporated into a cavity, it is to be expected a high finesse and very narrow spectral bandwidth.
◦It is provided two types of wavelength 532nm and 1064nm.

▶The super mirror coated on a concave substrate is available as custom. Please specify the radius of curvature.
▶Fro products with different wavelengths, sizes, and incident angles not listed on-line or in our catalog, contact our Sales Division with your request.

Attention

▶When used as a single mirror, it does not transmit the light because the reflectance is high. Please use it after assembled to precise cavity in order to use transmitted light.
▶Please make a measurement or handling of the mirror in the clean environment. The dirt, dust and gas contamination will cause a significant effect on the measured value.
▶If a cavity is consisted of two plane mirrors, the output light may become unstable. In order to realize the stable cavity, please change the mirror of one side or both into a concave mirror, and build a cavity.
▶The Super Mirror has an extremely long lead time manufacture and test resulting in longer delivery than simple products on-line and in our general catalog. Please consult our Sales Team in advance when ordering.
