摘要

提出了一种仅根据实验透射率数据确定薄膜厚度、折射率和消光系数的直接优化计算方法。与传统方法不同，该方法不依赖于任何色散模型。数值和实验分析证实了该方法的准确性。折射率和消光系数的变化曲线表明了硫系化合物薄膜的化学键性质。这为分析光学薄膜的光学参数提供了一种有用的方法。

Direct optimal calculation method for obtaining the thickness and complex refractive index of chalcogenide glass films

A direct optimal calculation method was proposed to determine the thickness, refractive index, and extinction coefficient of thin films solely from experimental transmittance data. Unlike conventional approaches, this method does not rely on any dispersion model. Numerical and experimental analyses confirm its accuracy. The variations in refractive index and extinction coefficient curves demonstrate the chemical bond properties of chalcogenide films. This work provides a useful method for analyzing the optical parameters of the optical films.
