Request InfoIDEX Health & Science - Semrock Optical FiltersSemrock Inc. has released a line of optical edge filters for Raman spectroscopy and fluorescence imaging. The EdgeBasic long-wave pass filters have a typical transmission of 98% and an optical density >6. The filters provide extended light blocking from the laser wavelength to deep into the ultraviolet spectrum to enhance their suitability for fluorescence applications. They are hard-coated with an ion-beam-sputtering deposition process for durability and reliability even in harsh conditions. The filters are housed in a black-anodized aluminum ring that is 25 mm in diameter and 3.5 mm...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra May 2024 IssueBandpass Optical FiltersThe Semrock Nanopede™ Optical Filters from IDEX Health & Science cover the near UV and visible spectrum 20 nm full-width, half-max steps.
