Abstract
An optical apparatus for a near-eye display includes a microdisplay to emit image light and one or more field lenses positioned to receive the image light from the microdisplay. The one or more field lenses have a combined optical power to form a curved intermediate image. A freeform combiner, having an eyeward side and an external side, is positioned to receive the image light from the one or more field lenses and reflect the image light. A curved intermediate image is formed between the freeform combiner and the one or more field lenses.
