Spectroscopy analyzer using a detector array

摘要

An apparatus for analyzing a spectrum includes an elongated source of light, a device for producing a spectrum of the light, a sample stage, and an array of photosensitive elements for detecting the spectrum and providing an output representative of an intensity of the spectrum as a function of wavelength. The sample stage is interposed between the elongated source and the spectrum-producing device. The light propagates along a length of the sample stage from the elongated source to the spectrum-producing device. The elongated source has a length greater than or equal to a length of the array.
