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: Y!0ZwwW
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. eGEeWJ}[$
37楼说对了,挺厉害。 V']{n7a-
