    ARO has extensive experience depositing and optimizing Anti-Reflective (AR) Coatings for laser applications. In our industry, every photon of light matters. That’s why we have designed our AR coatings to optimize transmission through your optical components by minimizing front and backside reflection losses. AR Coatings are typically applied to windows and lenses to reduce reflection losses to optimize the transmission through the optic. ARO can also apply AR coatings to the backside of optics including polarizers and partial reflectors to minimize back side reflection. ARO has the capability to optimize AR coatings for narrow, multiband, and broadband specifications. We have custom AR coatings available from 193nm to 3000nm with particular experience optimizing 193, 248, 308, and 1063 nm coatings.

    Anti Glare Coating

    AR Coating performance depends on multiple specifications. Material selection, coating deposition type, material, bandwidth, angle of incidence, and wavelength are all factors to consider when designing your optimal AR Coating. ARO can select from E-beam, magnetron sputtering, IBS, and ion-assisted deposition coating techniques based on your environmental, laser damage threshold, and wavelength requirements. AR coatings can be applied to a wide range of substrate material including FS, CaF2, MgF2, BK7, and others. ARO is able to reach the lowest reflectivity specifications for narrowband coatings at normal incident angles. Broadband AR coatings see a trade-off between bandwidth and reflectivity.
