Abstract

A method for aligning multiple optical components in an optical system including placing a sphere at a first position that is at a center of curvature of a first optical component, and aligning a focus of a first reference signal with the sphere at the first position. Then, moving the sphere along an axis of optical symmetry to a second position that is at a center of curvature of a second optical component, and aligning a focus of a second reference signal with the sphere at the second position. The first optical component is aligned with the first reference signal and fixing the first optical component, and the second optical component is aligned with the second reference signal and fixing the second optical component.
