【摘要】：浮法玻璃作為鍍膜產(chǎn)品的基片,分析其光學(xué)常數(shù)是進(jìn)行產(chǎn)品光學(xué)設(shè)計及質(zhì)量控制的基礎(chǔ)。由于反射光無法完全體現(xiàn)材料吸收特征、玻璃兩個界面的多次反射光產(chǎn)生退偏問題,使利用橢偏原理分析浮法玻璃光學(xué)常數(shù)存在局限性。本文利用分光光度計測量浮法玻璃300~2500 nm范圍透射光譜,根據(jù)光譜特征,建立以高斯振子及極振子為核心的復(fù)合振子模型,共15個未知參數(shù),利用遺傳算法依據(jù)透射光譜數(shù)據(jù)分析獲得最佳振子參數(shù),得到相應(yīng)的光學(xué)常數(shù),符合浮法玻璃基本光學(xué)特性。
[Abstract]:Float glass is used as substrate for coating products. The analysis of its optical constants is the basis of optical design and quality control. Since the reflected light can not fully reflect the absorption characteristics of the material, there is a depolarization problem caused by the multiple reflection of the glass interface, which makes the analysis of the optical constants of float glass by ellipsometric principle have some limitations. In this paper, the transmission spectra of float glass in the range of 2500nm are measured by spectrophotometer. According to the spectral characteristics, a composite oscillator model with Gao Si oscillator and polar oscillator as the core is established. There are 15 unknown parameters. The optimal oscillator parameters are obtained by genetic algorithm based on the transmission spectrum data, and the corresponding optical constants are obtained, which accord with the basic optical properties of float glass.
