Abstract:
    An infrared light source used in spectrometers including an infrared range, a Fourier Transform Infrared Spectroscope (FTIR), etc. The infrared light source is composed of a panel made of sintered silicon nitride plates, a heating element made of metal and embedded in the panel, and a pair of conducting lines for supplying electricity to the heating element. The infrared light is emitted homogeneously from the flat surface of the panel, as compared to a conventional infrared light source using a metal filament in which infrared light is emitted inhomogeneously. It is preferred to form a silicon oxide layer on a surface of the panel to prevent initial change in the infrared emitting characteristic.
