【摘要】：为了研究单轴晶体铌酸锂双折射滤光片的温度特性,采用计算机进行数值理论分析,讨论了入射光方向上铌酸锂晶体双折射率和厚度随温度变化的关系,并利用Ultra-6600系列紫外-可见分光光度计对铌酸锂滤光片进行了光谱测量和实验验证。结果表明,在不同波段的滤波带宽,可以找到某些特定的入射角度,使滤光片的中心波长不随温度变化而变化,双折射滤光片温度的稳定性可以保持。此结果说明,可以通过调节入射光方向来提高滤光片的温度稳定性和使用精度。
[Abstract]:In order to study the temperature characteristics of uniaxial crystal lithium niobate birefringent filter, the relationship between the birefringence and thickness of lithium niobate crystal with temperature in the direction of incident light was analyzed by computer. A series of Ultra-6600 UV-Vis spectrophotometer was used to measure and verify the spectrum of lithium niobate filter. The results show that some specific incident angles can be found in the filter bandwidth of different bands, so that the central wavelength of the filter does not change with temperature, and the temperature stability of birefringent filter can be maintained. The results show that the temperature stability and operating accuracy of the filter can be improved by adjusting the direction of incident light.
