Model 122 Kilimanjaro Probe Station

The Model 122 Kilimanjaro Cryogenic Probe Station offers a cryogenically robust platform for low-temperature device probing. Unlike systems whose actuators are placed at 300K, our probe station uses translation stages that are thermally anchored at 4K. This reduces sample temperature elevation due to manipulator arm heat leak.

The Model 122 Probe Station can be configured to host either individual chips or whole wafers. Other options include translations up to the full diameter of the wafer, window shutters, coaxial cables and sample magnets.
