本文描述近红外消色差施密特系统的优点。它对两个波长消球差、残余球差满足斯特列尔-瑞利判据。用几个数字例子说明了所述的理论。
This article describes the advantages of a near-infrared achromatic Schmidt system. It cancels the ball on both wavelengths and the residual spherical error satisfies the Stirrell-Rayleigh criterion. The theory is illustrated by several numerical examples.
