Patent ID: 6970736

Claim:
An analysis system of matter adhered to an inside wall of a vessel comprising: a guiding apparatus including a main body portion, a flexible inset portion extending from said main body portion and being able to be inserted said vessel and having a window formed in a distal end thereof, and a channel extending through said menu body portion and insert portion and reaching said window, and a Raman analysis apparatus including a light source emitting an excitation light, a spectroscope spectrally analyzing said matter adhered to the inside wall of said vessel, a flexible insert cable to be inserted into said channel and whose distal end is faced with said window, an excitation optical fiber being received in said insert cable and whose basal end is connected to said light source for transmitting said excitation light and whose distal end is arranged at a central area of the distal end portion of said insert cable, a plural number of light receiving optical fibers being received in said insert cable and whose basal end are connected to said spectroscope and whose distal end are arranged in such a manner as to surround said excitation optical fiber at the distal end portion of said insert cable, a transparent excitation small piece having a film-like excitation optical filter adhered to a surface thereof and the surface being abutted against a distal end of said excitation optical fiber, said film-like excitation optical filter cutting all light only excepting a light having a predetermined wavelength, and a transparent light receiving plate having a film-like light receiving optical filter adhered to a surface thereof and the surface being abutted against distal ends of said plural number of light receiving optical fibers, said film-like light receiving optical filter cutting only a light having said predetermined wavelength, wherein said excitation light along said excitation optical fiber is projected through said window and Raman scattered by impinging on said matter adhered to the inside wall of said vessel, said scattered light is made incident to said window, and said incident light is transmitted along said light receiving optical fibers to said spectroscope for analyzing, and wherein said transparent light receiving plate has a center hole and said transparent excitation small piece is fitted into said center hole.
