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： #P-T4 R
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. eR:!1z_h
37楼说对了，挺厉害。 D=!5l 4
