为了测试温度对1310nm波段石英晶体旋光性的影响,采用高低温试验箱作为温控器,设计了双光路检测系统对石英晶体在1310nm波段旋光性的温度效应进行测试研究。实验结果表明,在-10～20℃温度范围内,对于确定波长的光,随温度的升高,石英晶体的旋光率增大;在25～50℃温度范围内,随温度的升高旋光率减小;对于同一温度,波长越长旋光率越小。根据测试结果求解Sellmeier方程得出了Sellmeier方程的常数与温度的关系式,从而可以得出任意温度下不同波长对应的石英晶体的旋光率。
In order to test the effect of temperature on the optical activity of 1310nm quartz crystal, a dual optical detection system was designed to test the optical effect of quartz crystal at 1310nm. The experimental results show that the optical rotation of quartz crystal increases with the increase of temperature at a temperature of -10 ~ 20 ℃, and the optical rotation of quartz crystal increases with the increase of temperature at a temperature of 25 ~ 50 ℃. Decrease; for the same temperature, the longer the wavelength the smaller the rate of rotation. Solving the Sellmeier equation according to the test results gives the relationship between the constant of the Sellmeier equation and the temperature so that the optical rotations of quartz crystals corresponding to different wavelengths at any temperature can be obtained.
