对《光电光谱仪》来讲,因工作环境温度的波动,将导至摄谱仪棱镜折射率的改变,从而使摄谱仪的色散率有所波动,再加上光电头材料的热胀冷缩,将不同程度地产生谱线的中心极大与光电头出射狭缝中心的相对位移。尽管一般光电头中均设有“温度补偿”调节机构,然而在温差较大的环境中工作时它却无能为力,若有条件,把整个仪器置于恒温室中当然好,从经济观点考虑,我认为局部恒温也可以。我们自制的局部恒温箱经多年来的实践证明:它控温精度高(±0.1℃)、稳定可靠、经济、能耗少、操作方便、使用安全。
The “photoelectric spectrometer” is concerned, due to fluctuations in the working environment temperature will lead to spectroscope prism refractive index change, so that spectrograph dispersion rate fluctuations, coupled with the photoelectric head material thermal expansion and contraction , Will generate different degrees of the center line of the spectrum and the photoelectric head exit slit center relative displacement. Although the general optical head are equipped with “temperature compensation” adjustment mechanism, but in the larger temperature difference in the work environment, it can do nothing, if conditions, the entire instrument is placed in the greenhouse of course, from a financial point of view, I Think local thermostat can be. Our self-made local incubator has been proved by many years of practice: it has high temperature control accuracy (± 0.1 ℃), stable and reliable, economical, less energy consumption, easy operation and safe operation.
