Magnetometers
Twinleaf sensors measure magnetic fields with unparalleled sensitivity, linearity, dynamic range, and bandwidth.
- PPM — Pulsed Pump Magnetometer. The highest performance magnetic field sensor that you can buy.
- OMG — Optical Magnetic Gradiometer. Same as PPM, but with two measurement locations to form a gradiometer. Measure small local signals underneath background noise.
- microSERF — Highest sensitivity, but only near zero field.
- VMR — A convenient and cost effective magnetoresistive sensor for measuring vector magnetic field. Not an atomic magnetometer.
Plus, Twinleaf sensors are easy to use with completely open-source software support in Python, C, Rust, Labview, and more.
Magnetic shielding
Twinleaf shields provide a volume with controlled magnetic field. The shields exclude environmental fields and noise, and have internal field coils to apply arbitrary magnetic fields to a central volume. Twinleaf magnetic shields make it easy to utilize the full performance of Twinleaf sensors in an office setting.
- MS-2 Magnetic Shield — Largest internal volume, ⌀18 cm × 36 cm, with highest field uniformity. ⌀4 cm access hole.
- MS-1L Magnetic Shield — Compact size: ⌀14 cm × 16 cm. ⌀3 cm access hole.
- MS-1LF Ferrite Magnetic Shield — A ferrite inner layer provides lower thermal noise floor.
- DG Degaussing Unit — Automatically de-gauss a shield.
Current supplies
Low noise current sources, ideal for excitation of magnetic field coils in Twinleaf shields. Compare.
- CSB — Current Supply, Bipolar, 3 channels, digital control: ±10 mA, ±50 mA, and ±250 mA.
- CSBA — Current Supply, Bipolar, Analog control: ±10 mA, ±50 mA, and ±250 mA.
