Frameless Fiber Coil
High-performance fiber coil winding optimized for low bias drift, tight tolerances, and long-term stability.
LumiHelix — Precision fiber coils
Precision in every turn.
FOG coils, built on-shore.
U.S.-made precision coils and optomechanical assemblies for defense, aerospace, and autonomous mobility — where supply chain and compliance cannot fail.
About & Technology
Built on 15 years of precision. Now built in America.

Drag to rotate
An interactive 3-axis fiber-optic gyroscope — counter-propagating beams through three orthogonal coils use the Sagnac effect to measure rotation in all axes, no GPS required.
15+ years of production-proven coil processes, exclusively licensed and paired with founder FOG expertise — built in an ITAR-compliant California facility.
Built for primes
Off-the-shelf, ITAR-compliant, procurement-ready coils for the integrators behind defense, aerospace, avionics, and autonomous navigation systems.
Day-one capability
Exclusive license to proven processes, custom winding equipment, and proprietary test methods — production-grade from coil one.
Custom Winding Systems
In-house systems engineered for high-performance coil geometries and winding patterns.
Proprietary Potting
Thermally conductive adhesives that hold performance through vibration and temperature extremes.
Superb Coil Winding
Proven octupole, quadrupole, and modified quadrupole patterns — industry-leading yield.
Comprehensive Testing
Proprietary in-process testing at every stage — every coil meets stringent optical and mechanical specs.
Competitive landscape
The only supplier purpose-built
for U.S. FOG integrators.
End-to-end capability from fiber to full optomechanical assembly — with the test coverage, compliance, and non-competing posture U.S. integrators need.
Markets & Applications
Why on-shore precision is winning — and why now.
Three forces are converging to reshape the fiber optic gyroscope supply chain. LumiHelix is built to meet the moment.
Autonomous mobility at scale
eVTOLs, autonomous vehicles, and robotics are scaling fast across civilian and defense — and demand for precision inertial sensing is outpacing supply.
Reshoring pressure
Tariffs, BABA defense mandates, and supply-chain fragility are forcing fiber coil production back on shore — fast.
FOG technology leadership
Fiber optic gyroscopes outperform MEMS and outprice ring-laser. Coil quality is the single biggest determinant of FOG accuracy.
Where the demand concentrates.
Three segment groups account for the vast majority of high-end FOG demand — each with distinct performance and compliance requirements.
Defense & Aerospace
Missile guidance, platform stabilization, and dynamic tracking for ITAR-bound programs and avionics-grade inertial reference.
Autonomous & Unmanned Systems
Land, air, and sea — from autonomous vehicles to drones, eVTOLs, loitering systems, and industrial and defense robotics.
Commercial Aviation & Satellites
Avionics where FOGs outperform MEMS at MEMS-class cost — plus attitude control and pointing for orbital platforms.
Team & Contact
Decades of photonics and
inertial-sensing experience.
