Bluefors Collaborates with Basel Precision Instruments on Cryogenic Filtering Solutions

Bluefors and Basel Precision Instruments have started a collaboration, integrating Basel Precision Instruments’ Microwave Filter & Thermalizer (MFT) into Bluefors’ cryogenic platforms. 

In experiments done at millikelvin temperatures, residual microwave noise and insufficient thermalization of signal lines can prevent samples from cooling to the same temperature as the rest of the cryogenic measurement system. This collaboration addresses that by combining Bluefors’ expertise in cryogenic measurement systems with Basel Precision Instruments’ specialization in low‑noise cryogenic filtering and thermalization. 

The Microwave Filter & Thermalizer is designed to suppress high‑frequency noise while efficiently thermalizing signal lines, helping electron temperatures at the sample more closely track the temperature of the dilution refrigerator. The MFT provides strong microwave attenuation, exceeding 100 dB above 100 MHz, and has been used in research setups where sample temperatures as low as 7.5 millikelvin have been achieved. 

By integrating the MFT into the Bluefors measurement infrastructure offering, customers can get these solutions ready to use and tested with their cryogenic measurement systems. The integrated solution supports lower noise levels, improved electron temperature performance, and reduced setup complexity, enabling more reliable and reproducible measurements in quantum computing, condensed matter physics research, and other ultra low temperature applications. 

This collaboration reflects a shared focus on removing practical barriers in low temperature experiments, helping researchers spend more time on experiments and less on mitigating wiring related limitations.
