Optical Coating Materials

An optical coating is one or more thin layers of material deposited on an optical component such as a lens or mirror, which alters the way in which the optic reflects and transmits light.

MSE Supplies offers a wide selection of high-quality evaporation and crucibles in a full range of purity and dimensions for thin film optical coatings. These materials are suitable for all commercial evaporation systems, whether your requirements are for thermal evaporation, electron beam deposition system and ion sputtering system.

For evaporation, we provide pure metals, metal fluorides, metal oxides, metal fluoride, metal selenides & sulfides evaporation materials. These materials are typically available in bulk forms like pellets, pieces, wires and powders. We can customize the evaporation materials in dimensions, composition, and purity upon request. We also provide other evaporation materials for non-optical coating purpose.

For ion sputtering, we provide sputtering targets with customized chemistry, geometry and dimensions.
