Abstract
A mount includes an active area in which an optical element may be located. The mount is bonded to a neighboring mount using adhesives that are placed on a top side of a wall structure of the mount. Migration of the adhesives from the wall of the mount into the active area is prevented by use of groove-structures and micro-wall structures located in a buffer area of the mount that circumscribes the active area. In some embodiments, a diffuser is located in the buffer area of the mount to redirect the emitted light as desired for a particular application.
