Claim 16:
17. The Raman spectroscopy equipment according to claim 14, wherein
the second light focusing lens, the long pass filter, and the third collimator lens are configured:
to concentrate the first scattered light from the second front optical fiber through the second light focusing lens;
to form the first scattered light in parallel between the second light focusing lens and the long pass filter;
to change the first scattered light to second scattered light through the long pass filter;
to form the second scattered light in parallel between the long pass filter and the third collimator lens; and
to transmit the second scattered light to the second rear optical fiber through the third collimator lens, and
the long pass filter shields elastically scattered light of the first scattered light and allows inelastically scattered light to pass therethrough such that the inelastically scattered light corresponds to the second scattered light.
