Precision magnetic field sensors

Twinleaf creates high-performance magnetic field sensors and related equipment.

SERF-2 Compact vector atomic magnetometer

Sensitivity better than 5 fT. Try these instead of SQUIDs!

Twinleaf's magnetic field sensors feature the highest sensitivity available per unit sensor volume, utilizing the spin-exchange relaxation-free (SERF) regime in an atomic vapor. All-optical, fiber-coupled atomic magnetometers provide lower interference and application flexibility. Complete sensor systems are available for purchase and new systems are under development.
