COATED OPTICAL COMPONENTS
AR, Reflective, Filter and Protective Coatings for Optical Systems
Optical coating performance depends on both the thin-film design and the component beneath it. COE supports coating solutions for precision optical lenses, optical windows, mirrors and filter substrates across UV, visible and infrared systems.
AR and BBAR coatings improve transmission at selected wavelengths, while metallic or dielectric reflective coatings support beam steering and imaging. Bandpass, longpass and shortpass designs provide spectral control for optical filters. Protective solutions, including application-specific coatings for germanium optics, help components withstand demanding handling and environmental conditions.
For SWIR, MWIR and LWIR thermal imaging, coating designs are reviewed together with substrate transmission, operating band, angle of incidence and durability requirements.
