At present, with the rapid development of the spectral industry, fiber optic spectrometer is becoming more and more recognition in the domestic, the product performance and quality almost same compared with foreign products. Fiber optic spectrometer due to its advantages of high accuracy, high speed, has become an important measure to spectrum used in the surveying instrument is widely used in agriculture, biology, chemistry, geology, food safety, chromaticity calculation, environmental inspection, medicine and health care, LED, semiconductor industry, petrochemical industry, etc. Spectrometer has many important parameters, which is particularly important is the stability of the instrument, the stability of people's heart, once the stability is bad, the instrument is almost obsolete. There are many factors that can influence the stability of the instrument, general instrument factory, the stability is relatively fixed. Below we fiber optic spectrometer, for example, let's discuss. In order to effectively guarantee the stability of the spectrometer tried many kinds of methods, to explore a feasible solution, it directly through to the hardware to do special processing, without calibration algorithm software, realize the high and low temperature ( - - - - - - 10° - - - - - - 60° ) The nearly zero. 1 drift. This value can be done at home and abroad. As is known to all, light path of spectrometer and detector are inevitably changes with the environment, for example, the change of environmental temperature will lead to the spectrometer wavelength ( The X axis) The drift. Optical path and detector do special processing can enhance the long-term stability of the spectrometer. However, these special processing will increase the hardware cost of the spectrometer. Some spectrometer manufacturers, in order to save cost, do not do the hardware processing. Leading to the stability of the instrument will become poor. Spectrometer in the future in the new century will be highly intelligent and the trend of miniaturization, micro spectrometer is a kind of miniature device. Miniature device is, in fact, which has the function of instrument MEMS/MOEMS products, is the practical application of MEMES technology. Miniature device is one of the core technologies of the micro sensor technology, all kinds of sensors used in a variety of new principles, new concept is the key to the realization of miniature device and the necessary conditions. Now toward the development of micro miniaturization, intelligent instrument make we face a new test, the development of an opportunity.
