Planar lens and method for fabricating the same |
摘要 |
A planar lens capable of compensating for chromatic aberration and which is easy to manufacture and enables easy assembling of optical pickups and a method for fabricating the planar lens are provided. The planar lens includes a transparent substrate with a lens cavity in a surface of the transparent substrate, and a lens element formed in the lens cavity with a first refracting surface in contact with the bottom of the lens cavity and a second diffracting surface having a diffraction grating opposite to the first refracting surface.
