Request InfoOptiGrate Corp.OptiGrate Corp. has unveiled 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. Using a single-stage spectrometer, Stokes and...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.
