According the light-reflecting principle,a small specular-reflecting device has been designed,which can be applied to determine the brightness,the color and the thickness of stainless steel coloured film successfully in one-step,with a spectrophotometer and correcting the transmittancy.
利用光反射原理,设计出一小型镜面反射装置,借助可见分光光度计,通过校正透光率,一步准确地测定出彩色不锈钢着色膜的亮度、颜色与厚度。
