Abstract

The projection lens system is designed for the head mounted projective display (HMPD) system to provide a wide field of view up to seventy degrees. The lens is optimized from a double-Gauss lens composed of two singlet lenses, one diffractive optical element (DOE) lens, one aspheric lens and a stop surface in the middle of the lens said lens has a focal length as low as approximately 23.9 mm whereby it has a field of view (FOV) of up to approximately 70 degrees and more. The lens can be combined with an additional field lens whereby the resulting lens combination provides improved image quality and/or field of view beyond approximately 70 degrees.
