Oxford Instruments offer a selection of low pass multi-stage filters for our 24 way DC looms.The low pass filters are available in four different cut-off frequencies and are compatible with our dilution refrigerators.
These can either be fitted in the factory with the system, or can be purchased separately, or as an upgrade to your current system.
The filter is constructed in a gold plated copper chassis with RF gaskets to provide screening and thermal dumping for the filter PCB.
The surface mount filter components are selected to provide excellent value stability over a wide cryogenic temperature range which is demonstrated by the consistency of response between the room temperature and 4K performance.
Four cut-off frequencies available between 170 Hz and 110 kHz.
