Optics Manufacturing

I have worked both hands-on and in a process engineering capacity with optics ranging from 1.5 mm to 2.56 m in diameter; thickness down to 90 mm; with materials of all types including a range of glass, metals, gain crystals, nonlinear and birefringent crystals; with hardness ranging from NaCl to Al2O3; in configurations including flat, radius, prism, cylinder, aspheric, multi-surface, lightweight, water-cooled, gas-cooled, and assemblies. I've also developed tooling, fixturing, handling and test methods for unique projects. I developed and taught a six-month apprentice program for a major laser manufacturer that brought new-hires to the level of five- to ten-year veteran opticians; and have presented training programs for several major precision optics companies' technicians.
