Being both an optical manufacturing facility and a thin film coating facility allows Precision Optical to provide excellent support to our customers. In-line with this vertically integrated approach to our business, we compliment our manufacturing prowess with engineering and CNC machining. This allows us to develop custom thin film coating designs utilizing the latest powerful thin film software. Custom thin films are only functional with substrates. And substrates, particularly complex geometries, require carefully designed tooling. This tooling must be capable of safely and securely holding the optical substrates, while allowing optimal coating coverage onto the surface being coated. There is both an art, and science to designing the perfect coat tool!
