Abstract: A novel soft beamsplitter mounting system as part of an interferometer to protect the beamsplitter substrate from external stresses and thus preserve optical flatness is introduced. The soft mounting system enables such protection by being more flexible that the beamspitter substrate so external forces deforms the mount rather than the beamsplitter. Although the soft beamsplitter mounting configurations disclosed herein protects the beamsplitter, the interferometer itself is less stable because the mounts of the present invention allows the beamspltter to tilt more easily than other components held in the interferometer. The improved tilt control embodiments of the present invention turns this seemingly deleterious effect into a cost saving benefit by using the inexpensive soft mounting system as a flexure to allow an improved active control system to maintain tilt alignment in a system that is more rugged than conventional interferometers.

Abstract: The invention provides a method for standardising an infrared spectrometer based on spectral patterns of constituents of atmospheric air naturally occurring in the spectrometer. The invention also provides a spectrometer applying the method. The method selects a spectral pattern in a recorded spectrum and determines a wavelength dependent position value for a feature, such as the centre of the pattern. This value is compared to a reference value that may be obtained from a spectrum recorded by a master instrument, and a standardisation formula can be determined. The absorption peaks from CO2 (g)around 2350 cm-1 are preferred as the selected pattern. The method renders the use of reference samples unnecessary and allows for the standardisation to be performed simultaneously with the recording of a spectrum of a sample of interest.
