TFHSM

A Fabry-Perot resonator cavity is often used for measuring extremely high accuracy time or distance with use of the light. Our Super mirrors are ultra-high performance mirrors which provide near 100% reflection in order to maximize the performance of the resonator.

◦ Reflectivity’s of 99.999% and 99.995 respectively, are achieved from our coating design and manufacturing process technology that has been developed over several years.
◦ By incorporating ion beam sputtering (IBS), these high density optical coatings yield superior performance and yield minimal surface defects.
◦Low-scattering substrates with surface flatness Ra<0.1nm through special polishing and metrology techniques.
◦Scattering loss from the substrate and the coating is extremely small. When these mirrors are incorporated into a cavity, they will yield high finesse and narrow spectral bandwidths.
◦OptoSigma currently offers two standard wavelengths 532nm and 1064nm.
◦Inquire within for custom wavelengths and output coupler
