Founded in 1957, RMI began as a manufacturer of traditional optical components. Today, RMI has evolved into a world class operation that includes the design and manufacturing of full spectrum (Deep Ultraviolet through Far Infrared) optics, thin film coatings, optical assemblies, and opto-mechanical components for laser and imaging applications.

Since purchasing the company in 1983, Dr. Yubong Hahn, a recognized expert in high power thin film coatings, has transformed the RMI Optical Division from a seven person optical shop into an established player in the photonics industry and a leader in the production of the highest quality precision optics.

RMI has established a high degree of experience working with several major industries, including Medical, Defense, Semiconductor, Industrial/OEM, and Research and Development. Our custom capabilities and new material production facility allow us to make some the highest quality optical products for companies all over the globe.
