Request InfoOptiGrate Corp.ORLANDO, Fla., Oct. 1, 2010 — OptiGrate Corp. has launched BragGrate, a line of ultranarrow notch and bandpass filters for Raman spectroscopy applications. The filters have a bandwidth of <10 cm-1, which the company says is about 10 times narrower than other notch and bandpass filters commercially available for these applications. The filters enable measurements of ultralow frequency Raman bands with standard instruments, rather than with the previous complex, bulky and more expensive tools. Applications include nanotechnology, pharmacology and semiconductor processing. Stokes and anti-Stokes frequencies...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.
