  • Planar diffractive optical element lens and method for producing same
    Patent number: 9366877
    Abstract: A planar diffractive optical element (DOE) lens is described herein. The planar DOE lens includes a substrate. The planar DOE lens further includes a first layer, the first layer being formed upon the substrate. The planar DOE lens further includes a diffractive optical element, the diffractive optical element being formed upon the first layer. The planar DOE lens further includes a second layer, the second layer being formed upon the first layer. The second layer is also formed over the diffractive optical element. The second layer encloses the diffractive optical element between the first layer and the second layer. The second layer includes a planar surface.
