HighFinesse Precision Current Sources have been developed for experiments and quantum technologies in the areas of cold-atom and solid state physics. The linearly regulated BCS (Bipolar Current Source) and UCS (Unipolar Current Source) series deliver highly stable, low noise source currents for high precision magnetic field control.
The current output is either floating or on a used defined potential. Ultrafast response to control signals and trigger functions, clear grounding, connection and signal isolation schemes make the integration of the current sources into complex experimental systems easy.
- Current range: 20mA - 200A
- Voltage range: up to 40 Volts
- Adjustable response time: 50µ to 100ms
- Low noise: -120dBA/√Hz @10-100kHz

Available systems:
Milliamp Line: Compact & Mobile With Battery Supply up to 20 mA
The compact micro- and milliampere precision current sources generate currents proportional to an analog control voltage. The sources are supplied from batteries integrated in the housing of the source together with a recharger unit. Full functionality for controlling micro- and milliamps on ultra fast time scales and at ultra low noise level.

Compact Line: Compact Bipolar Current Sources
The BCS line (up to 20 A) comprise all functions of a precision current generator in a compact device. The linearly regulated bipolar current generators deliver highly stable, low noise source currents for high precision magnetic field control. The current output is either floating or on a used defined potential. Ultrafast response to control signals and trigger functions, clear grounding, connection and signal isolation schemes make the integration of the current sources into complex experimental systems easy.

SMD Line: Modular & Mobile
The SMD Line pushes the performance of the bipolar current source to the limits. With compact circuit boards and SMD components, the sources are reaching the lowest noise level and fastest response. The modular design allows the selection of operational units that are most important for the desired application, leaving out other modules. The sources can be supplied from the mains or from external batteries. Ideal for mobile systems. An optional manual control module and digital display make operation of the source easy also in standard lab applications.

Power Line: Purest Power up to 200 A
The water cooled unipolar (UCS) and bipolar (BCS) current sources deliver up to hundreds of Amps with so far unprecedented precision and fast response. The constant low temperature of the water cooled power electronics results in extremely high stability and low noise figures. The Power Line feature all comfortable control units. The operation of the Power Line is just as easy as of any other of HighFinesse’s current source.
