Abstract
An optical system assembly technique utilizes a templating system for locating optical components 200 on optical benches 150. Specifically, the template system comprises a template substrate 102 that is placed over the optical bench. The substrate 102 has at least one alignment slot 104 that is formed through the substrate. This alignment slot 104 has an alignment feature 120, against which an optical component 200 is registered. In order to improve the accuracy of the alignment of the optical component on the optical bench, the slot 104 has a reentrant, such as a smooth or step, sidewall 106 extending from the alignment feature 120 into the template substrate 102. This way, there is a single point or near single point of contact between the optical component 200 and the template 102, to thereby improve the placement precision for the optical component on the optical bench 150.
