Optical Coating Materials

Materion is an industry leader in high-quality specialty optical coating materials for the optics industry, including defense, aerospace, ophthalmics, laser optics, communications, sensing, and medical applications.

To support the fabrication of optical components in wavelengths from ultraviolet (UV) to far infrared (IR), we offer evaporation materials and sputtering targets for optical coatings that cover more than 70% of the periodic table, including fluorides, oxides, and precious and non-precious metals.


Our fluorides and oxides are available in a variety of purities and forms, including granules, pellets, and powders. This allows us to partner closely with our customers to develop custom compositions and meet challenging design criteria. In addition to our optical coating materials, we are also a leading supplier of sputtering targets for optical coatings, including Tantalum (Ta), Silicon (Si), Hafnium (Hf), and Niobium (Nb) targets and Gold (Au) and Silver (Ag) products and services for high reflectors and contacts.
