Request InfoDiCon Fiberoptics Inc.DiCon Fiberoptics Inc. has modified its Miniature Tunable Filter to include a captured o-ring sealed tuning screw for improved feel and precise tuning. The center wavelength can be tuned over 15 nm with 0.5-dB bandwidths as narrow as 0.8 nm. Additional benefits include 0.05-nm tuning resolution, 0.05-dB typical polarization dependence loss and 1-dB insertion loss. A new package design provides excellent environmental protection. The filter is suited for panel or printed circuit board monitoring.See full productRelated content from Photonics MediaPRODUCTSPromoted Content August 2022 IssueNew Filters Enable Compact, Lower Cost FluorometerDelta Optical Thin Film has introduced new advanced excitation and emission bandpass optical filters for fluorescence spectroscopy/microscopy that enable more compact and lower cost fluorometers to...BioPhotonics 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.
