Abstract
In an aspect, an optical device includes a substrate, a light source mounted on a top surface of the substrate, and a lid attached to the top surface of the substrate, the lid defining a reflective cup positioned over the light source. In another aspect, an optical device includes a substrate, a light source disposed on the substrate, and a lid disposed on the substrate. The lid defines a reflective cup for concentrating and passing light from the light source. The optical device further includes a film formed on an inner sidewall of the reflective cup for reflecting the light from the light source. The film includes a primer layer, a reflecting layer and a protective layer.
