Abstract

An optical system for use in an apparatus capable of spectral analysis comprises a housing for housing a reference sample, and a reference sample collector within the housing wherein the reference sample collector collects light scattered from the reference sample. The housing may include a director for directing light from a source towards the reference sample. The reference sample may be mounted for movement to provide different distances between the reference sample collector, perhaps a focusing optic, and the reference sample. A further self illuminating reference source may be provided. The reference sample may comprise a photodiode and means to sense electrical current at the p-n junction of the photodiode. Also disclosed is a spectrometer comprising a reference sample wherein light from a source within the spectrometer may be optionally directed by a director towards the reference sample and light scattered from the reference sample collected by a reference sample collector.
