Abstract

The invention discloses a front annular halogen tungsten lamp light source, and relates to light source of near-infrared miniature spectrographs. The front annular halogen tungsten lamp light source includes eight halogen tungsten lamps (1), a light constraint (2), a threaded pillar (3), a half-open holding rod (4), a simple drive circuit (5) and a protective cap (6). The eight halogen tungsten lamps (1) are evenly arranged on the light constraint (2) to form an annular structure. The threaded pillar (3) and the simple drive circuit (5) are arranged in the light constraint (2). The halogen tungsten lamps (1) are connected with the simple drive circuit (5). The half-open holding rod (4) is meshed with the tail end of the light constraint (2). The protective cap (6) is meshed with the front end of the light constraint (2). The annular halogen tungsten lamp light source is arranged in the front, therefore the complexity of the light source design is lowered, the energy usage rate of the light source is improved, the detection area is enlarged, more comprehensive spectral information is obtained, and the portability of the near-infrared light source is improved. The near-infrared spectrum is detected conveniently, the size of the near-infrared spectrographs is reduced, and the development cost of the spectrograph is reduced.

Description

technical field [0001] The invention relates to a light source for a near-infrared miniature spectrometer, in particular to a front ring tungsten halogen light source. Background technique [0002] As an efficient scientific analysis tool, the near-infrared micro-spectrometer has been widely used in the fields of agricultural products, petrochemical products, food and environmental detection. With the increasing requirements for the portability of spectrometers in research and applications, designing an integrated light source with simple structure, easy use and high stability has gradually become the development trend of the best accessories in the field of spectrometer detection. At present, the vast majority of commercialized near-infrared light sources are discrete modules of spectrometers, consisting of "Y"-shaped fiber optic probes, fiber-coupled optical path structures, drive circuits, heat sinks, and power supplies. The light source needs to be connected to the outp...
