Request InfoKnight OpticalGlass-Precision Grade Aspheric Lenses from Knight Optical LLC are used to correct spherical aberration in lasers and imaging. The nonspherical surface of an aspheric lens allows a single component to effectively focus or collimate even highly divergent emissions, potentially replacing a multi-lens system with a single aspheric lens. The lenses feature visible antireflective coatings.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra July 2022 IssueFluorescence Filter SetKnight Optical LLC’s fluorescence filter set range suits the diverse needs of various fluorescence applications that demand high-quality components.
