Advanced Thin Film Coatings
The finishing element of any precision optical component is the coating. The coating is not only critical for managing energy transmission and reflection, but also preservation of the wavefront quality. Many people 
have experienced how most coatings can degrade the optical quality of precision mirrors. Stress intraditional metallics and MLD coating can add up to 200 MPa of load to the surface of the optic. Our dielectric coatings have less than a 10% this always. We achieve this by meticulously controlling the structure of each layer we deposit and design our coatings not only for their spectral requirements but also for preserving the wavefront. No other coating company guarantees this – however, we must because we make the optics too.
