OSI

What OSI does

Optical Scientific, Inc. (OSI) is a privately held Gaithersburg, Maryland manufacturer founded in 1985 that develops optical scintillation-based sensors for environmental and industrial monitoring. The company's core technology uses infrared optical beams to detect scintillation patterns from precipitation or air-mass movement, then converts those signals into rain rate, wind speed, turbulence, and visibility values via proprietary DSP algorithms and environmentally adaptive AI. Its product portfolio is organized into four families: weather sensors (ORG-815 Optical Rain Gauge, APG-815 All Precipitation Gauge, OWI-430/OWI-650 Weather Identifier and Visibility Sensors), emissions and process flow sensors anchored by the OFS-2000 for EPA 40 CFR Part 75 stack gas compliance, atmospheric turbulence products led by the LOA-005 long-baseline optical anemometer (100 m to 10 km range), and FAA-certified automated weather observing stations (AWOS-AV, MAWOS) including the acquired Belfort AWOS product line.

OSI sells primarily through direct B2B channels targeting airports, federal agencies (NWS, FAA, NASA, USAF, USGS, NOAA), transportation authorities, industrial facilities (power plants, refineries, smelters), and research institutions; pricing is quote-based in USD EXWorks Gaithersburg with open-account terms for North American buyers and letter-of-credit terms internationally. The revenue model combines capital hardware sales, instrument repair and refurbishment services, and custom environmental monitoring station integration. The installed base includes 1100+ first-generation LEDWI sensors operating 25 years on in the NWS ASOS program and global deployments from Antarctica to Saudi Arabia. Recent strategic actions include the 2025 Anduril Industries EagleEye defense AR helmet partnership, expansion of the OFS line into flares, wet scrubbers, and particulate mass flow, and acquisitions and certifications (ISO 9001:2015, CE) that broaden both the addressable market and regulatory footprint.
