Femto Sensing International

What Femto Sensing International does

Femto Sensing International (FSI), founded in 2018 and headquartered in Atlanta, Georgia, designs and manufactures Fiber Bragg Grating (FBG) optical sensing interrogators, expansion modules, and monitoring software for industrial, civil, energy, transportation, security, medical, and research applications. The company operates a wholly owned subsidiary of Technica Optical Components, LLC, with manufacturing in Singapore and Atlanta, and applications engineering and software support in Sweden. FSI's product portfolio spans four tiers — premium FAZT series (ultimate 0.1pm precision, 50fm repeatability via licensed FAZ Technology), industrial-grade MX series (1-32 channels, economy tier), commercial-grade SX series (static/dynamic measurements), and the newer W-series with 160nm wide scanning plus portable/mini form factors. Core technology centers on a solid-state semiconductor tunable laser with no movable parts, delivering world-leading MTBF and operating across -40°C to +75°C.

The company monetizes primarily through quote-based hardware sales of FBG interrogators and expansion modules (including the M64S4 expansion module enabling up to 1,920 sensors per system), supplemented by contract engineering services for application-specific configuration, software engineering, training, and installation. Pricing is enterprise direct with multi-year contracts; software (Femtosense, PicoSense, NANOSENSE, PicoSense X, PCS Logger) is bundled free with compatible interrogators. Distribution is direct-to-enterprise via the website and a global applications engineering team covering the USA, Canada, Sweden, Japan, China, and South Korea, with no disclosed reseller or distributor network.

FSI holds ISO 9001, CE, RoHS, EX, and IECEx certifications, supporting sale into hazardous-environment and regulated industrial segments. The company's competitive positioning rests on licensed patented FAZ Technology calibration architecture, US patented laser calibration, and an expanding product portfolio that has progressively broadened from premium to economy tiers since 2018. Recent strategic emphasis has shifted toward portable and field-deployable form factors and a unified cross-platform software ecosystem with industrial automation integration (MODBUS TCP, Fugro Georisk Portal). Leadership is anchored by CEO Andrei Csipkes and Director of Applications Engineering Ingemar Ernstsson; the company has no disclosed external institutional funding.
