Raman Filters

Longpass edge filters, dichroic mirrors, and narrow bandpass filters are important components of the core optical path of Raman spectrometers. All Raman filters use ion beam sputtering or plasma sputtering coating processes, resulting in a dense and robust film structure, with accurate and stable working wavelengths, meeting the needs of complex working environments such as outdoor conditions. Raman filter combinations can be provided according to different laser wavelengths, such as 532nm, 633nm, and 785nm. Since Raman spectroscopy has significant value for pure qualitative analysis and molecular structure determination, it is widely used in fields such as chemistry, physics, biology, and medicine.
