第二二向色滤光片408也可反射从第二波长转换元件412所发射的光，例如，绿光或红光。
The second dichroic filter 408 May also reflect light emitted from the second wavelength converting element 412, e. g., green or red light.
由于光盘信息符(坑点)尺寸可以和波长相比较或更小，标量衍射理论的有效性必需进行检验。
Validity of scalar diffraction theory must be checked, because the size of information mark (pit) of optical disk is comparable with or smaller than the laser wavelength.
如果LED亮度和波长不一致，做成大屏幕LED彩色显示屏后，会使观众产生斑点或刺眼的感觉，严重影响LED显示屏的质量，因此必须对LED单管进行分选。
It will affect quality and induce dazzling sight in large color-display if LED's wavelength and light intensity are not measured, so we must achieve auotmatic separation of LED.
而在减色法中，染料(比如在绘画颜料或彩色照相材料中)吸收了部分波长而只允许分光谱通过，从而产生各种色彩。
In the subtractive process, colors are produced when dye (as in paint or color photographic materials) absorbs some wavelengths and so passes on only part of the spectrum.
