准确测量多角度下镀膜玻璃反射色,是镀膜玻璃质控提出的新要求。本文比较了不同入射角度下使用分光光度计测得的反射光谱曲线与使用TFCalc软件计算的玻面理论反射光谱曲线,发现随着入射角度增加,分光光度计检测器接收的光信号由玻璃的多次反射光逐渐转变为仅有第一次反射光,导致测量光谱与人眼接收的实际光谱不符,给颜色计算带来偏差。利用椭偏仪分别测量了玻璃第一、二次反射对应的反射光谱曲线,提出将第一、二次反射光谱曲线对应做和后进行颜色计算的新方法。
It is of great importance for quality control to measure the reflected color of coated glass accurately at different incident angles.Spectral reflectance curves of the glass face were measured by using spectrophotometer,and curves corresponding to the first reflection of non-coated glass were calculated by TFCalc software.It is found that with the increase of incident angles,the detector of spectrophotometer can only receive the first reflected beam.It introduces error to the calculated color values.A new method was provided to measure the spectral curves of the first and second reflections respectively and then calculate color values by summing them.
