1. A spectrometer for analyzing a sample of material by utilization of an electromagnetic radiation source and a detectorcomprising:

  • a. a waveguide possessing an entry for admission of electromagnetic radiation from the source and an exit for the electromagnetic radiation emanating from the source, said waveguide further including a surface between said entry and exit portions, permitting interaction between electromagnetic radiation passing through said waveguide and a sample of material, said waveguide exit permitting electromagnetic radiation from the waveguide to pass from said waveguide;

    b. a tapered portion forming a part of said entry of said waveguide, said tapered portion coupling electromagnetic radiation emanating from the source to said waveguide;

    c. a substrate adjacent said waveguide, said substrate being capable of passing electromagnetic radiation from the source to said tapered portion forming part of said waveguide entry; and

    d. capturing means for directing electromagnetic radiation passing from said exit of said waveguide to a detector.
