Equipment and procedures have been developed for the fabrication of small nonsymmetrical aspheric surfaces. A grinding or polishing pad is used which is much smaller than the workpiece. The oscillating motion of the workpiece under the pad coupled with the grinding or polishing slurry produces material removal. Control over this removal is accomplished by varying the speed of the pad as it travels over different regions of the workpiece. The technique has been used to fabricate two nonsymmetrical aspheric metal mirrors.
已开发出用于制造小型非对称非球面的设备和工艺。所使用的研磨或抛光垫比工件小得多。工件在垫子下方的摆动运动与研磨或抛光浆料相结合可实现材料去除。通过改变垫子在工件不同区域移动时的速度来实现对这种去除的控制。该技术已用于制造两个非对称非球面金属镜。
