LNPS-80 Low Temperature Probe Station

The Vectomag LNPS-80 Low Temperature Probe Station provides a reliable platform for non-destructive electrical, optical, and microwave measurements on materials and semiconductor devices.

It supports device sizes up to 80 mm, making it ideal for research on nanoelectronic materials, quantum wires, quantum dots, and semiconductor structures.

The LNPS-80 offers precise temperature control from 80 K to 425 K, using liquid nitrogen cooling with a heat-shielded chamber that reduces blackbody radiation and minimizes LN2 consumption.

Its modular design allows users to configure probes, sample stages, and measurement cables for different experimental needs, supporting DC, RF, and microwave measurements.
