Abstract:
An analysis apparatus, said apparatus including:a housing, said housing shaped to define an enclosed chamber for receiving a specimen to be analyzed; a radiation source mounted to said housing, said radiation source configured to emit radiation at a first wavelength that is absorbed by a first substance in the specimen, said radiation source being mounted to said housing to emit radiation into the chamber; a first pair of spaced-apart receivers mounted to said housing, each said receiver configured to measure radiation at the first wavelength and being mounted to said housing to receive radiation from within the chamber; and a first pair of concave mirrors that are disposed in the housing chamber, said mirrors being shaped and positioned in the chamber to split the radiation emitted by said source into two separate beams of the radiation, each beam of radiation being directed to a separate one of said receivers that form said first pair of said receivers and so that the paths of travel of the radiation beams from said source to said receivers are of different lengths.
