感谢94楼,看到了原文。这篇光学系统设计时选择玻璃校正色差的方法,由于是英文的,看的不很透。但也有收获,该文举例的多光谱系统分别有各谱段的中心波长,还有一个共同的主波长。见原文: g? \pH:|79
the central values for each spectral band were used: 0.485, 0.55, 0.66, 0.83 and 1.6 microns. The primary wavelength λ0 was set to 0.83 microns the due to its proximity to the central wave of the whole spectrum covered by the instrument. fGLOXbsA
37楼说对了,挺厉害。 m<22E0=g
