本文论证了消除二种波长球差的施米特近红外消色差系统的优点,并给出符合斯特雷——瑞利准则的残余球差。用几个数例说明了这种理论。
This paper demonstrates the advantages of Schmitt near infrared achromatic systems that eliminate the spherical aberration of two wavelengths and gives the residual spherical aberration in line with the Stray Rayleigh criterion. A few examples illustrate this theory.
