Classification: CPC G  H | IPC G  H

Claim 0:
1. An optical system, comprising:
an image projector for producing light-waves corresponding to an image, the image projector including: an emissive display device configured to generate light corresponding to the image, and
an optical assembly configured to receive light from the emissive display device and output image light, the optical assembly including a base optical element and a plurality of lens optical elements arranged in a stack configuration;
a light-transmitting substrate having a plurality of surfaces including at least a pair of major external surfaces configured to guide light by internal reflection between the major external surfaces; and
an optical coupling-in configuration associated with the base optical element and a coupling-in region of the light-transmitting substrate, and configured to couple image light from the image projector into the light-transmitting substrate,
wherein the base optical element has a prism-shaped cross-section and is configured to modify the image light prior to the image light reaching the optical coupling-in configuration so as to at least partially compensate for chromatic aberration.
