FAQ
Q: What applications benefit most from the LCZ-01's sensitivity?
A: Its 15 fT/√Hz sensitivity makes it ideal for biomagnetism (e.g., magnetocardiography), geophysical surveys, non-destructive testing, and fundamental physics research requiring ultra-low field detection.
Q: Can it operate without magnetic shielding?
A: While functional in ambient fields <60 nT, optimal performance requires minimal interference. For high-noise environments (e.g., urban areas), passive/active shielding is recommended.
Q: How does dual-axis (Y/Z) measurement enhance data accuracy?
A: Simultaneous Y/Z-axis detection captures vector field components without device repositioning, critical for mapping field gradients or studying dynamic magnetic sources.
Q: Why is thermal management critical for SERF magnetometers?
A: Atomic vapor cells demand precise temperature control to maintain optimal density and minimize spin-exchange collisions. The LCZ-01's sub-50°C surface design ensures stability without external cooling.
