Influence of multiple-beam interference on transmittance of yttrium vanadate prisms
-
摘要: 为了系统地研究多光束干涉对钒酸钇棱镜透射比的影响,对棱镜的透射比进行了详细的理论分析,得到了不考虑多光束干涉和考虑多光束干涉情况下,800nm～2400nm波段棱镜透射比的理论曲线,并利用UV-3101PC分光光度计进行了实验测试,发现钒酸钇棱镜的透射比在近红外区随波长的增大呈上升趋势,且曲线有波动。结果表明,多光束干涉对棱镜的透射比产生扰动。这为钒酸钇棱镜在偏光器件中的应用提供了重要的参考价值。Abstract: In order to study influence of multiple-beam interference on the transmittance of yttrium vanadate prisms, transmittance from 800nm to 2400nm was theoretically analyzed taking multiple-beam interference into consideration or not. Experiments were carried out with a UV-3101PC spectral photometer. It is found that transmittance of the prism increases and vibrates with wavelength. The result shows that multiple-beam interference makes a disturbance to the transmittance of the prism. It is a good reference to the application of yttrium vanadate prisms.
