Abstract
In some implementations, an optical element comprises a glass substrate, a dark mirror coating disposed on a first surface of the glass substrate, and a lens disposed on a second surface of the glass substrate. An aperture is formed in the dark mirror coating, and the aperture is aligned with the lens. The optical element is a monolithic optical element.
