Abstract: A method of optical analysis comprises receiving light at an optical spectrometer module from a light source, distributing the received light into two or more light beams with a light distribution component of the optical spectrometer module, concurrently exposing each of a reference and one or more test samples to one of the two or more light beams, and concurrently measuring a property of the light associated with each of the reference sample and one or more test samples with a corresponding detector.

Abstract: The present invention is directed to a sample holder for use in molecular absorption spectroscopy. The sample holder comprises a first surface having a first predetermined geometry. and a second surface having a second predetermined geometry. The first surface is opposite the second surface. The sample holder is configured to hold a measurement sample between the first surface and the second surface such that a distance between the first surface and the second surface defines an optical pathlength of the sample holder. The predetermined geometries of the first surface and the second surface provides a continuously variable cross-section across the sample holder so as to provide a continuous range of optical pathlengths.

Abstract: An optical spectrometer module for analysing samples. The optical spectrometer module comprises two or more sample holders. Each sample holder is adapted to receive and reproducibly position a sample in fixed locations within the optical spectrometer module. Each sample holder is also adapted to receive a light beam to thereby enable a sample contained in the sample holder to be exposed to the received light beam. Each sample holder is further adapted to enable light transmitted through the sample holder to exit the sample holder. The optical spectrometer module also comprises two or more electro-thermal components. Each electro-thermal component is thermally coupled to a respective sample holder to control the temperature of the sample holder.
