What Rocky Mountain Instrument does

Rocky Mountain Instrument Co. (RMI), founded in 1957 and headquartered in Lafayette, Colorado, is a privately held precision optics manufacturer operating from a 90,000 sq. ft. vertically integrated facility. The company designs and manufactures custom optical components, advanced thin-film coatings, and opto-mechanical assemblies spanning the Deep UV (193nm) to Far IR (14µm) spectrum for mission-critical laser and imaging applications. Core technical capabilities include 15 thin-film coating chambers utilizing e-beam deposition, ion-assisted deposition (IAD), and indium tin oxide (ITO) processes; four diamond turning lathes producing aspheric IR lenses up to 12 inches in diameter; 250-spindle CNC machining; and one of the largest in-house environmental testing facilities covering adhesion, abrasion, temperature, humidity, salt-spray, shock/vibration, helium leak, and radiation testing. The company is owned by Dr. Yubong Hahn, a recognized expert in high-power thin-film coatings who acquired the firm in 1983, and shares its facility with sister company RMI Laser.

RMI serves five primary vertical segments: Aerospace & Defense (night vision, thermal imaging, UAV and missile optics, LiDAR), Biophotonics & Medical (surgical lasers, endoscopy, ophthalmology, diagnostic imaging), Semiconductor (DUV lithography, inspection and metrology optics), Advanced Manufacturing & Industrial (machine vision, laser processing, NDT), and Research & Development (scientific instrumentation). All products are custom-built to customer specifications under a quote-based pricing model with no public pricing or e-commerce channel; sales are conducted directly to enterprise OEMs and government customers, with specialized ITAR/EAR/FAR processes for defense accounts. RMI maintains ISO 9001:2015, ITAR registration (valid through 2025), MIL-SPEC (MIL-PR F-13830B, MIL-I-45208, MIL-Q-9858), RoHS, and Conflict Minerals compliance, and is CMMC/NIST prepared for defense cybersecurity requirements. The firm has approximately 150 employees, of whom 90+ are technical experts, and claims global customer reach through direct sales engagement and participation in SPIE Photonics West and SPIE Defense + Commercial Sensing tradeshows.
