New SERF-2 Compact vector magnetometer

Sensitivity better than 5 fT. Ideally suited for fMRI, ECG, EEG and general laboratory use. Replace your SQUIDs, never use cryogens again!

Our sensors feature the highest sensitivity available per unit sensor volume, utilizing the spin-exchange relaxation-free (SERF) regime. All-optical, fiber-coupled sensors provide lower interference and application flexibility.

Complete sensor systems are available for purchase and new systems are under development. Let us adapt our technology to your application. Call or email today to discuss your requirements.
