Request InfoThorlabs Inc.Thorlabs has extended its broadband sources into the IR spectral range with the addition of the SLS201 and SLS202, two fiber-coupled tungsten light sources for chemical, medical and biological spectral analysis. The sources come in two versions, both featuring a constant-intensity blackbody radiation spectrum that ranges from either 300 to 2600 nm (tungsten halogen) or from 450 to 5500 nm (tungsten). They have a built-in removable filter holder, allowing the placement of standard 1-in.-diameter spectral filters into the light path. The holder also can function as a sample holder for...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.
