Abstract
An optical system assembly technique utilizes a templating system for locating optical components on optical benches Specifically, the template system comprises a template substrate that is placed over the optical bench. The substrate has at least one alignment slot that is formed through the substrate. This alignment slot has an alignment feature against which an optical component is registered. In order to improve the accuracy of the alignment of the optical component on the optical bench, the slot has a reentrant, such as a smooth or step, sidewall extending from the alignment feature into the template substrate This way, there is a single point or near single point of contact between the optical component and the template to thereby improve the placement precision for the optical component on the optical bench
