For many years, attocube has been pioneering cryogenic confocal
microscopy. With the introduction of the attoCFM series of confocal
microscopes almost a decade ago, the optical investigation of single
quantum devices on the sub-micron scale at low temperature suddenly
became available as a standard tool for scientists worldwide. Today,
the attoCFM/800 is once again redefining the state-of-the-art for low
temperature confocal microscopy.
It combines the revolutionary concept of the world’s first cryo-optical
table with integrated low temperature objectives and the external
optics head of the attoCFM I. The researcher is provided with a complete
cryogenic confocal microscope system which arrives in his laboratory
fully integrated and tested. Accompanied by an on-site installation and
hands-on training by our experienced optics experts, this will jump start
your measurements, and enable useful research results in a minimum
amount of time. For more information on the confocal microscope setup,
please refer to 136.
