透光性透光性是视觉上感知到的材料的透光性。当涉及到所有类型车辆的窗玻璃、显示板和磁盘以及所有其他用人眼光度响应度(V(λ))评估透射率的样品的规格时,这一点尤为重要。透光率测量透光率是一种相对测量。它描述了在几何定义的辐射光束路径中测量亮度的信号差。测量既可以在没有测试样品(100%)的情况下进行,也可以在有测试样品的情况下进行。测量装置的光源必须具有与标准光源类型a、C或D50对应的光谱特征。接收器的光谱响应度必须与人眼的光谱响应度相匹配。LCRT-2005-S光透射测量装置LCRT-2005-S是专为薄,划痕和透明样品的光透射测量而设计的。D/O测量几何结构包括积分球光源和亮度测量装置。所述光源的监控探测器和所述接收器的监控探测器均装有二极管阵列。 The spectral measurement data enables precise simulation of the standard light spectra and the photometric responsivity spectrum of the receiver. The sample is aligned in front of the light source for measurement. The degree of light transmission can thus be determined through diffuse sample illumination for thin scratched samples as well.
