A super mirror is an ultra-high-performance optical mirror designed to achieve surface reflectance as close to 100% as possible, in order to maximize optical system efficiency and performance.

Our mirrors can have reflectance as high as 99.993 % for specified wavelength.

Using ion beam sputtering (IBS), we have deposited high-quality, dense coatings with minimal defects.

A specially ultra-precision polishing substrates, achieving a surface roughness of Ra < 0.1 nm, ensuring exceptionally low scattering.

Thanks to a coating design technology, we have achieved mirror reflectivity up to 99.999%.

With extremely low scattering losses from both the substrate and the coating, these mirrors are ideal for high-finesse optical cavities, enabling very narrow spectral bandwidths and exceptional optical performance.
