Products Description:custom as request


Optical coating is specified and designed to enhance or reduce the reflectance, transmittance, or polarization properties of optical components. Coatings can be made from one or more layers of dielectric, IR, or metallic materials. Each coating is designed for a specific wavelength or wavelength range.

Focus Technology provides either standard or custom coating designs, please look at following coating designs what we are doing.
