Request InfoPOG Precision Optics Gera GmbHPOG Präzisionsoptik Gera GmbH offers customized variable metallic neutral density filters and geometric beamsplitters with variable beamsplitting ratios. Transmission and reflection in an application are defined by a computer-generated geometrical beamsplitter. The calculation is achieved by a variable configuration of pixel size (starting from 2-μm edge length) in constant raster (50 μm by default, modifiable to customer specifications). The company’s software and photolithographic fabrication enable the production of linear and nonlinear patterns in varying sizes for prototype and...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra October 2023 IssueCoated Glass FiltersNVIS Coated Glass Filters from Abrisa Technologies are designed for night vision imaging systems and lighting displays.
