microSAM Total Field Magnetometer

Twinleaf has created a breakthrough, ultra-compact optical magnetometer with an integrated control unit. microSAM is a microfabricated total field optical magnetometer. Its small size and low power consumption enable a wide range of new precision magnetometer applications. Now in its fourth generation, microSAM features true centimeter-scale sensor size and true isotropic measurements (no dead angles).
