Request InfoFospia Co. Ltd.Luvantix manufactures some of the lowest index polymer claddings available for high-NA (numerical aperture) applications. Our lowest index product, PC 370, has a cured index of 1.370 at 850 nm. This results in NAs over 0.48 when employed with pure silica cores. PC 370 has high transmission and is useful for hard-clad silica applications, whether for fiber lasers or for transmission of other high-optical power lasers. PC 370 can also be used for recladding optical fibers that have been stripped for splicing, connectorizing or writing Bragg gratings. PC 370 is an established, standard product...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra February 2023 IssueMounted Color FiltersMounted Machine Vision Filters from Edmund Optics Inc. are color filters optimized for use with popular LEDs with ≥85% transmission and blocking capabilities.
