Abstract
A system for aligning a plurality of high-precision lenses in a lens train. Each of the lenses has at least two alignment tabs disposed around the perimeter of the lens. The lenses are aligned by placing the lenses in a jig having a plurality of high-precision alignment blocks. The lenses are attached to a lower-precision shroud, having slots that receive the alignment tabs. A gap-filling adhesive is used to provide a high-precision fit for the lenses in the shroud.
