Claim:
1. An ATR infrared spectrometer for analyzing a chemical composition of a sample, the ATR infrared spectrometer comprising: an elongated ATR crystal having an entrance face, a longitudinal axis, a width, a first longitudinal end, and a second longitudinal end; said entrance face being arranged at said first longitudinal end of said elongated ATR crystal; an infrared light detector line having a plurality of infrared-light-detecting regions and being arranged at said second longitudinal end of said elongated ATR crystal, wherein a first overall extent of all of the plurality of infrared-light-detecting regions of said infrared light detector line corresponds to said width of said elongated ATR crystal in a direction perpendicular to the longitudinal axis of said elongated ATR crystal; an infrared light emitter line having a plurality of infrared-light-emitting regions and being arranged directly adjacent to said entrance face of said elongated ATR crystal; said sample being arranged adjacent to said elongated ATR crystal between said infrared light emitter line and said infrared light detector line; said infrared light emitter line being configured to emit infrared light; said infrared light being emitted to directly enter said elongated ATR crystal via said entrance face and being guided in said elongated ATR crystal to said infrared light detector line thereby undergoing total internal reflection and interacting with said sample; and, said first overall extent being greater than a second overall extent of all of the plurality of infrared-light-emitting regions of said infrared light emitter line.
