Light Shaping Optics Fabrication

A main focus has been the development and continuous improvement of mastering techniques to produce high-precision surface structures that enable efficient light management. We are now in the fifth generation of laser writing mastering processes that produce a surface pattern in photoresist and can be later used for replication into a polymer, metal, or transfer into hard substrate.

In addition to the mastering we have developed a set of support processes from thick, uniform resist processing to deep reactive-ion etching that enables the creation of general surface patterns in a variety of substrates.
