Abstract
A compound optical assembly is constructed from a plurality of stacking elements for spacing, aligning, and retaining optical elements within the assembly. Stacking faces of the stacking elements are measured and low-order surface errors are extracted, represented by mathematical approximations having a primary angular frequency. The stacking elements including the optic holders are relatively oriented to promote complementarity between the low-order surface errors of mating stacking faces.
