The utility model has following advantages and good effect:
1. the power of the vacuum rice bubble halogen tungsten lamp of this light source is 0.6W/, and 8 are total to the detection demand that 4.8W can reach the halogen tungsten lamp light source of general more than spectrometer 10W, and vacuum halogen rice bubble halogen tungsten lamp, photochromic low, so heating is few, without the need to radiating module;
2. only access simple optical fiber, namely without the need to coupling fiber light path, reduce coupling loss, improve capacity usage ratio, also reduce cost;
3. devise simple drive circuit, make rice steep the work of halogen tungsten lamp normal table, reduce complexity;
4. comprise again the light restraining structure of fixing light path, can directly be close to measured object surface, prevent shake spectrum, also increase detection area, spectrometer is obtained and is detected the more detection information of thing;
5. design half-open bar of holding conveniently hold by and detect, have perfect portable degree, can be used for outdoor various detection place.
In a word, the utility model is preposition by light source, achieve the portable degree reducing light source design complexity, raising energy of light source utilization rate, increase detection area, the more comprehensive spectral information of acquisition and improve near-infrared light source, thus be conducive near infrared spectrum detection, the reduction volume of near infrared spectroscopy instrument and the development cost of lowering apparatus.
