Request InfoAlluxaUltraflat dichroic and polychroic thin-film filters that feature flatness of <0.1 wave rms and transmission of >95% have been launched by Alluxa. They achieve flatness by eliminating the high stresses of as-deposited traditional ion-based coating processes such as ion-beam sputtering and ion-assisted deposition. A proprietary technique uses a plasma hard coating process that produces low-loss, fully dense dielectric films with essentially net zero stress on the primary coated side. The films do not require the lengthy additional coating time of back-side compensation or require...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra November 2022 IssueEmission Line FiltersTwo Hydrogen Alpha (H-alpha) Emission Line Filters for astronomy applications have been announced by Alluxa Inc.
