A planar lens and ultra-low-loss method of making

The present invention provides ultra-low-loss plane lens manufacturing method, step 1. On a flat transparent substrate by vacuum ultraviolet thermal evaporation deposition on the way to a thickness Wg of the gain layer; Step 2. On the basis of the gain layer obtained in Step 1, using electron beam evaporation methods plated thickness Wm the metal layer; step 3. in step 2 above was coated flat film alternately periodic gain layer and the metal layer of the multilayer film; step 4. Finally, on the surface and then coated with a layer thickness Wg of the gain as a protective layer . This ultra-high-resolution lens, light-weight and thin thickness, and because it is a flat structure, easy to integrate and use.
