Notch and Bandpass Filters support Raman spectroscopy.

October 4, 2010

With bandwidth less than 10 cm-1, BragGrate(TM) Notch Filters and BragGrate(TM) Bandpass Filters enable measurement of ultra-low frequency Raman bands with standard instruments. Units are based on reflecting volume Bragg gratings formed in photosensitive glass material by holographic techniques with no organic, thermally or optically unstable materials. Able to withstand temperatures to 450°C, filters are available for Raman laser source wavelengths of 488, 514, 532, 633, 785, and 1,064 nm. Read More
