DOUBLET EYEPIECE FOR HEAD MOUNTED DISPLAY

摘要

An eyepiece for a head mounted display (“HMD”) includes a doublet lens that includes a first optical element and a second optical element. The first optical element has an entry surface to receive the display light from a micro display and a first coupling surface. The second optical element has an exit surface and a second coupling surface paired to the first coupling surface of the first optical element. The doublet lens is configured to direct the display light through the first coupling surface, the second coupling surface, and through the exit surface.

1. An eyepiece for a head mounted display (“HMD”), the eyepiece comprising:
a doublet lens including:
a first optical element having an entry surface to receive display light from a micro display and a first coupling surface, wherein the first optical element has a first Abbe number; anda second optical element having an exit surface and a second coupling surface paired with the first coupling surface of the first optical element, wherein the second optical element has second Abbe number different from the first Abbe number, wherein the doublet lens is configured to direct the display light to propagate along an optical path through the first coupling surface, through the second coupling surface, and propagate through the exit surface, in that order.
