Abstract
According to examples, an optical lens assembly for head-mount display (HMD) devices may include an optical lens configuration with a first optical element and a second optical element. The first optical element and the second optical element may be affixed together along a peripheral edge to form a gap between the two optical elements and may compensate chromatic dispersion characteristics. The optical lens configuration may also include a reflective polarizer layer, a quarter wave layer, and a semi-transparent mirror provided on selected surfaces of the optical elements. In some examples, the gap may be filled with air or an inert gas.
