Electro Optical Components

What Electro Optical Components does

Electro Optical Components (EOC), founded in 1996 and headquartered in Santa Rosa, California, is a value-added distributor and technical integrator of photonics components for the North American market. The company holds distribution and representation rights for multiple international photonics manufacturers — including FEMTO (Germany) for low-noise amplifiers and photoreceivers, smartGAS for NDIR and TDLAS gas sensors, SemeaTech for electrochemical hazardous-gas sensors, IFW (Innoweb) for SiC UV photodetectors, Xavitech for micro pumps, RealLight for sub-nanosecond DPSS microchip lasers, LBP Optics for laser mirrors, and i-TEC for micro thermoelectric coolers. Beyond pure distribution, EOC has developed its own branded EOC-SI spectrometer family spanning handheld, miniature fiber-optic, airborne, and scientific high-sensitivity variants, alongside a LUCI-M data acquisition and analog-to-digital control system and LUCI-10 amplifier interface software.

EOC's portfolio spans signal recovery (fixed/variable/balanced photoreceivers, lock-in amplifiers, voltage/current/charge amplifiers); gas and particle sensing (NDIR modules, TDLAS modules up to 200m, electrochemical sensors for NH3, HCN, HCL, AsH3, SO2, NO2, PID VOC sensors); UV/Vis/SWIR/Mid-IR detection (SiC UV APDs, SiPMs, thermopiles, pyroelectrics, scintillators); laser sources (266/355/532/1064/1535 nm microchip lasers, lamp-pumped solid-state, Raman-stabilized diode modules); and supporting components (precision optics, Faraday isolators, spatial light modulators, Pockels cells, IR filters). Notable end-use validations include smartGAS sensors on NASA's Mars Perseverance MOXIE instrument and Dermagnostix confocal fluorescence detection modules.

EOC's go-to-market is direct, quote-based technical sales conducted by phone, email, and its eoc-inc.com product catalog, supplemented by photonics-industry trade show participation. The company sells at a single-country/domestic scope (North America), serving scientific research, industrial manufacturing, medical/biopharma, environmental monitoring, semiconductor process safety, gas detection, spectroscopy, LIDAR, UV curing, and aerospace/defense customers. Pricing is project-driven and not publicly disclosed; transactions are customized on a per-specification basis. Revenue mechanics are one-time/integration sales rather than subscriptions or licenses.
