Abstract
Disclosed herein is a lens for a wearable projection system. The lens includes a holographic optical element embedded within the lens and covering a portion of the viewable area of the lens. The lens can be manufactured by providing a first lens blank, affixing the HOE to a portion of the first lens blank, and forming a second lens blank on the first lens blank to embed the HOE between the lens blanks.
Claims25
A method to manufacture a wearable display lens, comprising:
- providing a partial lens blank, the partial lens blank comprising a front surface and a back surface;
- applying a holographic optical element (HOE) to a portion of the back surface of the partial lens blank;
- placing the partial lens blank and the HOE into a backside mold, the backside mold comprising a cavity, the HOE disposed within the cavity;
- and
- filling the cavity with a lens material to form a backside lens portion on the partial lens blank, wherein the HOE is embedded between the partial lens blank and the backside lens portion.
