摘要： A light wave-guide optical element for use in a head-mounted display (HMD) or in a head-up display (HUD) includes an organic optical material, an anti-reflection stack and an organic optical cover. The organic optical material includes multiple bulging tips surrounded by a periphery plane. The anti-reflection stack conformally covers the bulging tips and the periphery plane. The organic optical cover correspondingly covers the anti-reflection stack, the periphery plane and the bulging tips.

摘要： A lens array includes a plurality of micro-lens modules. Each of the micro-lens modules includes a first lens group and a second lens group. The first lens group and the second lens group are arranged sequentially from an object side to an image side along an optical axis. An effective focal length (EFL) of the first lens group is f1, an EFL of the second lens group is f2, and the micro-lens modules satisfy a following condition: −0.2

摘要： A wafer level lens system includes a target lens and a wafer level lens group. The target lens includes a first surface, a second surface, and a first fitting structure. The second surface is opposite to the first surface. The first fitting structure is disposed at the second surface. The wafer level lens group includes a first transparent plate and a second fitting structure. The first transparent plate has a third surface and a fourth surface opposite to the third surface. The second fitting structure is disposed on the third surface. The first fitting structure is fitted into the second fitting structure, and there is a space encapsulated between the second surface and the third surface.

摘要： A projector includes a laser module for generating a laser beam and a wafer-level optics. The wafer-level optics includes a first substrate, a first collimator lens and a diffractive optical element, wherein the first collimator lens is manufactured on a first surface of the first substrate, and is arranged for receiving the laser beam from the laser module to generate a collimated laser beam; and the collimated laser beam directly passes through the diffractive optical element to generate a projected image of the projector.
