193-nm Lithography Opens Doors for Diffractive Micro-Optics
Design considerations and fabrication affect performance for a near-IR large-angle homogenizer for use in 3-D sensors based on time of flight. The field of diffractive micro-optics is playing an increasingly important role in today’s technology, from high-speed data communications to bar-code scanners, and even in one of the world’s most popular gaming interfaces. Now, advances in the tools available for the manufacture of diffractive optics have opened up additional opportunit...
