Mahadevan9-2017 Diffuser

A laster pointer is pointed through the diffuser, which shapes the pinpoint of light into a wide beam. Right: the diffuser used in this study in a hand wearing lab gloves.

Left: Light from a laser pointer is shaped into a wide and stable output using a beam-shaping diffuser. A carefully designed pattern is precisely molded into plastic polymers or directly into a glass substrate, creating micro-structures on the surface of the diffuser (inset). Right: The diffuser installed at the ARC 3.5m Telescope at Apache Point Observatory.
