How do I use high performance laser line bandpass and laser line longpass filters as pairs in raman spectroscopy?

In Raman Spectroscopy, a clean excitation signal is a vital component in ensuring accurate measured scatter data. Our high performance bandpass and longpass filters complement each other very well in this regard. The high transmission and narrow bandwidth of the bandpass filters eliminates signal noise and ensures only the desired laser line reaches the sample. The high blocking and narrow transition of the laser line filter then eliminates the excitation signal and allows accurate measurement of wavelengths very close to the laser line.
