See-through computer display systems with stray light management

A method of manufacturing an optical system, comprising:

• providing a display panel;
• locating the display panel on an optical axis, wherein the display panel comprises a curved emission surface, the curved emission surface including a first emission surface point where the optical axis intersects the curved emission surface, the curved emission surface having a first radius of curvature at the first emission surface point;
• providing a lens;
• locating the lens on the optical axis, wherein the lens has a curved lens surface, the curved lens surface including a first lens surface point, the curved lens surface having a second radius of curvature at the first lens surface point, wherein:
• the curved emission surface comprises a first side of the display panel, wherein the first side of the display panel is proximal to the lens,
• the curved lens surface comprises a first side of the lens, wherein the first side of the lens is proximal to the display panel, and
• the second radius of curvature is substantially equal to the first radius of curvature at the first emission surface point;
• and
• providing an optical element on the optical axis and between the first emission surface point and the first lens surface point, wherein the optical axis traverses the first emission surface point and the first lens surface point,
• wherein the curved emission surface is configured to transmit image light from the display panel through the curved lens surface to present the image light overlaid on a view of an environment associated with the optical system.
