Request InfoAndover CorporationSteep-edge longpass filters from Andover Corp. feature magnetron-sputtered hard oxide coatings. The devices yield deep rejection to >OD 4 and a sharp transition slope of 1 percent to very high transmission. The coatings are deposited on precision-polished fused silica substrates and do not employ any absorbing filter glass, making them suitable for high-temperature applications.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.
