Request InfoEdmund Optics Inc.TechSpec, ground UV fused silica diffusers, have been introduced by Edmund Optics Inc. The RoHS-compliant devices are available in diameters of 10, 15, 25 and 50 mm and in sizes of 25 × 25 mm and 50 × 50 mm. During manufacture, a 220-grit sandblast creates a diffuse surface on the UV fused silica substrate. Each substrate undergoes two orthogonal passes during the blast, resulting in filters that offer uniform diffusion across the surface.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra April 2023 IssueHolographic Notch FiltersMETA® holoOPTIX® Notch Filters from Edmund Optics Inc. and Meta Materials Inc. are large, flexible holographic notch filters.
