United Lens Company has a long tradition of service to the optical industry, and our commitment is ongoing to the industry, our customers and our employees. Since our founding in 1916 by Fileno DiGregorio, ULC has been under the same continuous family ownership, becoming the only true vertically integrated company in the optical industry. What separates United Lens from other suppliers is that we are the only company that can form, anneal, machine, polish and coat all at one facility.
Thin Film Coating
ULC provides a broad range of optical coating services, ranging from anti-reflection and protected or enhanced metal mirrors consisting of 1-9 layers, to dielectric polarizers and beam splitters consisting of 60+ layers. These coatings can be applied to optics up to 23″ in diameter, having various shapes and sizes, with either plano or curved surfaces. Prior to coating, all optics are either cleaned in one of our automated ultrasonic cleaning systems or hand washed in our class 1000 cleaning and inspection room.

All shields are verified for absolute reflection on our state-of-the-art, calibration maintained spectrophotometers. Our shields are commonly used in fiber laser machines for laser cutting and laser welding.
