Minekane teaches that Fig. 1 is a structural diagram of the densitometer of the invention. We note that the structure disclosed utilizes a photomal item 6, which transforms the light into a electrical signal. Therefore, we fail to find that Minekane teaches a spectrometer to obtain an evanescent spectrum of hydrocarbon sample. Finally, we turn to Fuller. Fuller is directed to a cladded optical fiber. We note that the Examiner relies on Fuller for the teaching of using halide materials for the optical fiber. We 9Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
