Claim 0:
1. An optical assembly comprising:
a substrate having a first surface and a second surface opposite the first surface, the first surface having a first curved profile and the second surface having a second curved profile;
a beam splitter on the first surface and conforming with the first curved profile of the first surface; and
a reflector on the second surface and conforming with the second curved profile of the second surface, wherein the optical assembly is configured to:
receive first light at the first surface, and reflect the first light at the reflector and subsequently at the beam splitter before outputting the first light from the reflector, whereby the first light is transmitted through the optical assembly at a first optical power; and
transmit second light through the optical assembly without reflection at the reflector, wherein the second light is transmitted through the optical assembly at a second optical power that is less than the first optical power.
