Abstract
An optical element devices and method are described herein. An example optical device may include an optical element. The optical element may have an optical path material to allow a light to pass therethrough. The optical path material may have a first end portion with a first end surface, a second end portion with a second end surface, and a middle portion between the first and second end portions with an interior and an exterior surface. A coating may be disposed along the exterior surface and diffused into the optical path material. The coating may minimize leakage of the light from the interior through the exterior surface.
