Bluefors-Afore-The-Cryogenic-Wafer-Prober-2019

The Cryogenic Wafer Prober

The Cryogenic Wafer Prober, released in 2019, is developed to make automatic wafer probing at cryogenic temperatures well below 4 K possible. We have combined our expertise of building cryogen-free cryogenic systems with a neighboring company Afore, who has long experience in building automated wafer level test systems. Together we created the Cryogenic Wafer Prober. This tool allows up to 100 times faster throughput in sample characterization and we foresee that it will dramatically help speeding up the developments of cryogenic quantum devices, electronics and detectors.

Temperature Controller

The Bluefors Temperature Controller enhance the user experience of our cryogenic systems. With a modern and intuitive user interface, you gain direct control and overview of the system’s temperature status.

The Bluefors Temperature Controller is fully-integrated to all dilution refrigerator measurement systems.
