It's an easy matter to observe chromaticaberrations, with a thick, simple converging lens.
用一厚的简单会聚透镜很容易观察色差。

The dispersion caused from the chromaticaberrations of lens is smaller than that from diffraction effects of it.
与衍射效应产生的色散相比,透镜本身的折射率色散很小。

According to the effect of Angle errors on the chromaticaberrations of an optical system, we also derive the principle of determining Angle errors of a prism.
