Abstract
Spectrometer plays an important role, and is already an indispensable analytical instrumentation especially in biomedical, chemical and other fields. Instrument miniaturization will expand its application areas. And miniaturization design for all parts of optical path is the key to the whole task. This paper focuses on the research of the luminous source system design used in broad-band (200nm~1100nm) spectrometer. Considering the source wave band, a combination of deuterium lamp and tungsten lamp are chosen. According to the structure of the source, the main work concerns a collecting agglutinate lens and an elliptical reflector which acts as a light coupler. The optical design and the overall structure's optical path are simulated. On the basis of optical design and the selection as well as manufacture of the key components, the light source optical system of the project was analyzed experimentally and the results are satisfactory.
