Request InfoMaterion Balzers Optics JenaUsing thin-film optical filters to select a single wavelength band, the filters are usually completed by color glasses that reject the unwanted wavelength regions by absorption. However, high power of illumination makes it impossible to reject radiation by absorption without the risk of damage to the color glasses. In this case, the rejection of radiation has to be made by reflection on the filter. With UV applications, an additional problem occurs because of absorption loss in the thin-film materials used. mso jena now offers low-loss thin-film optical filters based on HfO2 and SiO2 thin...See full productRelated content from Photonics MediaPRODUCTSPromoted Content October 2023 IssueOrder Sorting FiltersWhen the spectrum of a spectrometer covers more than one octave, the multiple orders from the grating make interpretation of the detected spectrum difficult.
