Abstract: A waveguide lens, including: a waveguide substrate, wherein a diffraction grating is provided on a side surface of the waveguide substrate; a filling layer, wherein the filling layer is provided in a filling manner on a side of the diffraction grating that is away from the waveguide substrate; a low-refractive-index transparent layer, wherein the low-refractive-index transparent layer is connected with the filling layer; a first glass cover plate, wherein the first glass cover plate is bonded to a side surface of the low-refractive-index transparent layer that is away from the waveguide substrate; and a second glass cover plate, wherein the second glass cover plate is bonded to another side surface of the waveguide substrate. The problem of it being difficult to simultaneously take lightweight and imaging stability of a waveguide lens in the prior art into consideration is solved.

Abstract: An optical apparatus and an augmented reality device are provided. The optical apparatus includes an inner surface. The inner surface includes a predetermined region serving as a curved mirror with a predetermined optical parameter for reflection imaging of a virtual image of a virtual world. The optical apparatus further includes an outer surface. The outer surface and the inner surface are used for refraction imaging of a real image of a real world. The virtual image and the real image are integrated for forming a scene of augmented reality.
