从色度上说明目视望远系统透过率的表示方法,以实例进行了有限波长透过率的简化计算和测试。对某些望远镜“发黄”问题得出色度上的解释和度量,分析指出减轻或消除“发黄”现象的方向。 From the chromaticity to illustrate the visual telephoto system to express the method of transmission, an example of a limited wavelength of light through the simplified calculation and testing. Chromatographic interpretation and measurement of some “yellowing” problems of some telescopes are analyzed, and the direction of alleviating or eliminating the “yellowing” phenomenon is pointed out.
