Optical Thin-Film Coating Deposition

Vacuum evaporation of dielectric layers to create anti-reflection, high-reflection, and bandpass optical coatings. Uses thermal or electron-beam sources to deposit controlled-thickness films (50-1000nm) monitored by quartz crystal microbalance or optical interference. Restores vintage optics and creates custom filters.

Six Million Hertz Minus What the Coating Weighs

A 1 Hz frequency drop means 0.06 nanometres of coating. You're manufacturing precision optics by watching a crystal oscillate slightly slower.
