Abstract

An integrated optical assembly including a light management component with an entry surface and a light delivery component having an exit surface attached to the entry surface of the light management component is disclosed The light management component and the light delivery component are attached together in a manner that defines voids between the entry surface of the light management component and the exit surface of the light delivery component. The voids between the light management component and the light delivery component may provide an air interface over substantial portions of the entry surface of the light management component.
