ABSTRACT:
A compact and robust imaging Raman spectrograph has a collimating input lens assembly, a spectral filter assembly, a transmission diffraction grating, a focusing lens assembly, and a light detector. The spectral filter assembly is located between the two lenses and comprises a notch or long-pass filter optical interference filter, a plurality of optical channel plates for limiting the optical acceptance angle of the light passing the optical interference filter, and a transmission diffraction grating, all mounted in a single assembly. The spectral filter assembly permits a very high degree of elastically scattered light rejection and excellent stray-light reduction and management, while permitting a high level of optical throughput to maximize the signal of the weakly scattered Raman signal.
