OSI Optoelectronics

What OSI Optoelectronics does

OSI Optoelectronics is a Hawthorne, California-based designer and manufacturer of standard and custom photodiodes, optical sensors, and laser-based subsystems, organized as a wholly-owned subsidiary of OSI Systems, Inc. (NASDAQ: OSIS). The company operates 12 facilities totaling more than 380,000 square feet across the United States, Singapore, Malaysia, and India, with an in-house semiconductor foundry for silicon and III-V compound (GaAs, InP) wafer fabrication. Its portfolio spans silicon photodiodes (200–1100nm), InGaAs photodiodes (700–1700nm), GaAs photodiodes (400–850nm), avalanche photodiodes, position sensitive detectors, laser diodes, LEDs, X-ray detector/scintillator arrays, and FDA-cleared pulse oximeter sensors sold under sub-brands including UDT, Advanced Photonix, OSI Laser Diode, OSI Laser Scan, BluSat, and AME.

The company sells through a B2B OEM supplier model with direct regional sales teams (Americas, EMEA, Rest of World), custom design-and-manufacturing services from concept to volume, and catalog distribution via Digi-Key and Mouser. Pricing is quote-based and not publicly disclosed, with multi-year contracts typical for design-in programs. The customer base spans five verticals: Aerospace & Defense (space-qualified sun sensors on hundreds of spacecraft, missile guidance, LIDAR, FOG gyros), Medical & Life Sciences (CT scanner arrays, pulse oximeters, glucose monitoring, bone densitometers), Industrial/Test & Measurement (process control, bar code scanners, OTDR), Optical Communications (400G/800G transceivers, DWDM monitors), and Safety & Security (X-ray imaging, vehicle detection via the OSI Laser Scan product line).

OSI Optoelectronics is differentiated by an unusually broad stack of regulatory qualifications — AS9100D (aerospace), ISO 13485:2016 with MDSAP (medical), MIL-PRF-19500 and MIL-STD-883/750 (defense), Telcordia GR-468 (optical comms), and ISO 14001 (environmental) — across multiple sites, plus proprietary technologies including the industry-first 400–1700nm extended visible PSD and proprietary scintillator crystal combinations. The business was founded in 1967 as United Detector Technology, evolved through Opto Sensors, Inc. and OSI Systems (IPO 1997), and was consolidated under the OSI Optoelectronics brand in 2006 after successive acquisitions of LaserScan (2003), Laser Diode Inc. (2011), Advanced Photonix (2018), and Semicoa (2020).
