1. An optical assembly comprising:
- a stack of optical elements, wherein a first one of the optical elements has a first alignment feature tracing a curve along a surface of the first optical element, and a second one of the optical elements has a second alignment feature tracing a curve along a surface of the second optical element, wherein the first alignment feature fits within the second alignment feature, andwherein each of the first optical element and the second optical element has a shape that includes a respective first pair of flat side edges opposite one another and a respective second pair of rounded side edges opposite one another;
the optical assembly further including a housing laterally surrounding the stack of optical elements, wherein the housing has an inner surface shaped to match the shape of the optical elements.

Abstract
Optical assemblies include a stack of optical elements each of which has one or more alignment features. Each alignment feature traces a respective curve along a surface of one of the optical elements. The alignment feature(s) of one optical element fit within the alignment feature(s) of the other. In some cases, the alignment features can help establish more precise lateral alignment of the optical elements.
