Request InfoUnited Lens Co. Inc.For over 45 years ULC has been providing high-quality Thin Film Coatings for the photonics industry. We use a robotic multi-station aqueous ultrasonic cleaning system. All loading of fixtures is executed in Class 100 flow benches in a class 1,000 cleanroom. Once substrates are safely under vacuum, in-situ ion pre-cleaning completes the process of generating pristine surfaces to ensure maximum coating adhesion. The optics, ranging in size from 1/4” to 23” are coated in cryogenically pumped, computer-controlled chambers ranging from 45” to 72”.
