ABOUT
SYSTEM FEATURES
Capable of measuring 100mm large samples
This capability is made possible by the revolutionary design of our probe arm. Unlike traditional arms limited to X, Y, and Z-axis adjustments, we have innovatively integrated an R-axis (in-plane rotation) function.
The best OEM components
Sumitomo cryocooler, Pfeiffer pumping system, and GGB Industries probes, combined with our state-of-the-art expertise in cryogenic design and machining.
No liquid helium consumption is required
The PSM-4K is our premium cryogen-free, closed-cycle probe station, ideal for users who want the convenience of cryogen-free operation. With a self-contained closed-cycle refrigerator (CCR), it reaches cryogenic temperatures autonomously, removing the need for ongoing monitoring by the researcher.
Focused on innovation and flexibility
Temperature difference sample holder; R-axis in-plane rotation function; DC probes and optical fibers can be installed simultaneously on same probe arm. 100mm full surface probing…
Low Vibrations on sample stage
Provide a horizontal and vibrationdamping
support platform. Gravity vibration damping & air flotation vibration damping pads. Sample Stage vibration < 1µ p-p xyz (frequency range covers 0 to 100KHz)
Up to 6 probe arms
The types of probe arms can be freely combined;
· Four DC probe arms + two optical fiber arms, four DC arms + two 67GHz microwave
arms, three DC arms + two microwave arms + one optical fiber arm, etc. can be selected.

reviews
photo gallery
We searched for a long time, across three continents, for a manufacturer that truly had something to bring to researchers in Europe.
The cryogenic probe-station offering available on the market needed to be renewed, and researchers needed more competitive pricing for this type of system.
With LinkPhysics, Qnity has found the perfect challenger: undeniable innovations, the best OEM components, and ultra-affordable prices.
Above all, it addresses one of the main pain points expressed by researchers: the ability to probe larger-diameter wafers at cryogenic temperatures using a manual, laboratory probe station.
They’ve done it – we’ve seen it – and we’re going to tell everyone.
