Paper Abstract

A method for aligning off-axis aspheric surfaces has been developed. Normally, the vertex of a rotationally symmetric surface is used in the alignment procedure. This point, however, is not always found on the off-axis aspheric surface. The alignment procedure employs mechanical techniques to center this virtual point and optical techniques to remove the surface tilt. A mechanical jig, alignment telescope, and wire test device are all the equipment required. Expected alignment accuracies are discussed. A procedure for aligning an off-axis aspheric with unknown parameters is outlined.
