LCT-1A Full-Range Atomic Magnetometer
Overview
The LCT-1A redefines portable magnetic field sensing through advanced M2 optical-pumping technology. Engineered for field deployment and industrial applications, this magnetometer combines laboratory-grade precision with exceptional environmental resilience. Its modular design separates the ultra-compact sensor from the driver unit, enabling flexible installation in confined spaces while maintaining 2 pT/√Hz sensitivity. Integrated laser control and non-magnetic heating systems ensure stable operation across diverse environments, supported by intuitive software for real-time data acquisition and analysis.

FAQ
Q: How does M2 optical-pumping technology benefit field applications?
A: Unlike SERF sensors requiring near-zero fields, M2 technology maintains accuracy in Earth's magnetic field (≈50,000 nT), eliminating bulky shielding for mineral prospecting or pipeline inspections.*
Q: Can the sensor-driver separation distance be extended?
A: Yes. The shielded cable allows ≤5 m separation, enabling sensor placement in hazardous zones (e.g., boreholes) while the driver remains accessible.
Q: Why choose 70 Hz bandwidth for geophysical use?
A: This range optimally captures telluric currents and subsurface conductivity variations while filtering high-frequency EMI from power lines or machinery.
Q: How does the 3W power consumption enhance operational flexibility?
A: Ultra-low power enables continuous operation via portable solar arrays or lithium batteries – critical for multi-day surveys in remote areas.
