SAN CLEMENTE, Calif., March 26, 2015 — Reynard Corp. has begun offering custom photolithography services to manufacture patterned optics with geometries as small as 5 μm on substrates up to 18 in. in diameter. The process involves a contact exposing technique and a variety of thin-film coating. Metallic or dielectric materials can be selected based on the application’s transparent, reflective and conductive optoelectronic requirements. Patterns can be applied to most substrate materials, including plastic sheeting. Patterned optics applications include eliminating electromagnetic interference (EMI) for sensitive metal-coated electro-optical systems, heated windows, wideband beamsplitters, encoder disks, LCDs, bar codes, reticles, transducers and precision reference targets.
