BragGrate™ Raman Filters from OptiGrate are unmatched in the industry for narrow linewidth, optical density, and optical transmission. BragGrate notch filters enable measurements of ultra-low wavenumber Raman bands in the THz frequency range down to 4 cm-1, while at the same time, provide a broad transmission band that covers the complete frequency range +/- 4000 cm-1. This new generation of BragGrate Raman filters are available in 2016 at standard wavelengths such as 488, 514, 532, 633, 785, and 1064 nm as well as any custom wavelength from 355 nm to 2.5 microns. Our laser line cleaning filters (BragGrate™ Bandpass Filter), with a linewidth narrower than 5 cm-1 at FWHM, condition beams from laser diodes, solid state, or gas lasers, which are used for ultra-low frequency Raman measurements. OptiGrate Corp is a pioneer and world leader in commercial volume Bragg gratings (VBGs) and VBG-based ultra-narrow band optical filters.
