An achromatic Schmidt design is proposed for use in twin instruments at Kitt Peak and Cerro Tololo (Chile). The use of an achromatic plate, rather than the conventional Schmidt plate, allows extended spectral coverage by virtue of improved aberration correction. The improvement in geometrical blur diameter appears to be on the order of three times or an improved light concentration of nine times. Some schemes to convert the Schmidt to a Cassegrainian telescope during bright moon periods are evaluated; the choice would be determined on the basis of acceptable mechanical assemblies and economic factors.
一种消色差施密特设计方案被提议用于基特峰和托洛洛山（智利）的双仪器中。使用消色差板而非传统的施密特板，由于像差校正得到改善，可实现更宽的光谱覆盖范围。几何模糊直径的改善似乎达到三倍左右，或者光集中度提高九倍。评估了一些在明月期间将施密特望远镜转换为卡塞格伦望远镜的方案；选择将根据可接受的机械组件和经济因素来确定。
