Quantum optics experiments often require cryogenic temperatures in combination with optical access to the sample space. Most experimental setups contain numerous optical elements that need to be precisely arranged on an optical table to shape and prepare the incident light, as well as to efficiently collect and convert the emitted light from the sample. The available space on the optical table in such cases is of paramount importance to many complex setups.

attocube‘s attoLIQUID2000 superconducting magnet system is based on highly efficient liquid Helium bath cryostats with 50 l cryogenic liquid reservoir, but also includes a variable temperature insert (VTI) for convenient temperature control in the range between 1.8 K and 300 K. The system includes all necessary components needed for the operation such as the renowned attoDAMP anti-vibration cabinet with acoustic damping, a suitable rotary pump for the VTI, a dual channel temperature controller, a liquid helium level meter and probe, a transfer line and all necessary vacuum fittings.

attocube‘s attoLIQUID1000 liquid helium cryostat is based on highly efficient liquid Helium bath cryostats with 50 l cryogenic liquid reservoir. As with the whole attoLIQUID family, the attoLIQUID1000 has been optimized for highest stability, enabling experiments such as ultra high resolution imaging and/or spectroscopy using scanning tunneling microscopy (STM) or long-term optical investigations of single quantum dots over several weeks. All of attocube‘s available scanning probe microscopy inserts are compatible with the attoLIQUID1000 and are cooled by a controlled exchange gas atmosphere in thermal equilibrium with the surrounding liquid Helium.
