Optical coatings are 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.

Our products are available either coated or uncoated. If coated, we can provide either standard or custom coating designs.
