Patent ID: 7239782

Claim:
A chemical imaging fiberscope for imaging and collecting Raman spectra from a sample comprising: one or more laser illumination fibers for transmitting laser light of a specific laser excitation wavelength from a first source to said sample; a plurality of collection fibers, for receiving light scattered from said sample; a first portion of a spectral filter positioned between said one or more laser illumination fibers and said sample for transmitting said laser light of a specific laser excitation wavelength and rejecting light of other wavelengths; and a second portion of the spectral filter positioned between said sample and said plurality of collection fibers for transmitting wavelengths of light other than said specific laser excitation wavelength; wherein the spectral filter is spatially patterned into the first portion for filtering said laser light and a second, transparent portion for transmitting light scattered or reflected by said sample to said plurality of collection fibers.
