CPC classification number: G01J3/0205 , G01J3/0272 , G01J3/2803 , G01J3/36 , G01J3/44 , G02B6/4215 , G02B6/4298 , G01J2003/1213
Abstract: A spectrometer for studying a sample comprises a light guide for receiving light from the sample. The received light is emitted by the light guide through an exit surface that is on a side of the light guide and extending in a longitudinal direction of the light guide. The light emitted through the exit surface is filtered by a linear variable filter having an array of bandpass filters extending alongside and adjacent the exit surface. The filtered light is detected by the photodetectors of a detector array disposed parallel to the linear variable filter, and signals of the photodetectors are analyzed to obtain a spectral distribution of the light from the sample.
