Waveguide lens

The utility model provides a waveguide lens. The waveguide lens comprises a waveguide substrate, wherein a diffraction grating is arranged on the surface of one side of the waveguide substrate; the filling layer is arranged on the side, away from the waveguide substrate, of the diffraction grating in a filling mode, and the surface of one side of the waveguide substrate is completely covered with the filling layer; the low-refractive-index transparent layer is connected with the filling and leveling layer and located on the side, away from the waveguide substrate, of the filling and leveling layer; the first glass cover plate is bonded with the surface of one side, far away from the waveguide substrate, of the low-refractive-index transparent layer; and the second glass cover plate is bonded with the surface of the other side of the waveguide substrate. The waveguide lens solves the problem that the waveguide lens in the prior art is difficult to give consideration to light weight and imaging stability at the
