Super Mirror
페이지 정보
본문
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.
