Long-Wave Pass Filters
ROCHESTER, N.Y., Dec. 17, 2012 — Semrock Inc. has announced expanded wavelengths for the EdgeBasic line of long-wave pass edge filters. Ten laser wavelengths have been added to the previous 19. The filters offer steep edge locations from 325 to 1319 nm, with extended blocking at and below the laser line, which is combined with consistent and extended high-transmission passbands.
The filters were designed from the glass up and are suitable for fluorescence imaging and metrology applications. Used in application-specific Raman spectroscopy, they are a good fit when high laser-line blocking is required and the Raman shift measurement is not too small. They have hard-coated, no-burnout durability that is backed by a five-year warranty.
