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.
