Request InfoMaterion Balzers Optics JenaAll-dielectric edge filters with broad-band blocking have been introduced by mso jena GmbH. The multilayer coatings on a single substrate provide high optical densities over stopbands between 350 and 1100 nm. The company says that the coatings, applied by plasma ion-assisted deposition, provide environmental stability and shift-free performance, increasing the choice of substrate material and thickness. Typical parameters include transmittance >90% in the passband and optical density >5 in the stopband. Cut-on or -off wavelengths can be adjusted.See full productRelated content from Photonics MediaPRODUCTSPhotonics Showcase April 2024 IssueHHV Precision Optical ToolsHHV Ltd.’s optical deposition tools are designed for research and production of precision optical films on lenses, prisms, and domes.
