Request InfoEdmund Optics Inc.Edmund Optics has introduced linear variable filters designed for individual and combined use for maximum versatility. Available in long- and short-pass versions, they are manufactured with an interference coating that is intentionally wedged in one direction, creating a linear shift of the center wavelength across the length of the entire substrate. The shift enables broad filtering capabilities. The short- and long-wave filters work inversely to one another. The former passes light throughout the filter’s length until a blocking band is reached, while the latter blocks light until a...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics May/Jun 2023 IssueBandpass FiltersThe ADVANTECH™ hard coat bandpass filters from Andover Corp. offer steep slopes, high light transmission, durability, and long life for demanding applications.
