CUSTOMER FEEDBACK
Dr. M. Kroner
The confocal microscope attoCFM II together with the liquid dilution
refrigerator system from attocube provides a unique platform for optical
spectroscopy & microscopy at ultralow temperatures. Its flexible design,
fast turnaround times and remarkable long term stability make it a perfect system for elaborate long term experiments at high magnetic fields,
but also for quick sample testing. Besides, the first-class support from
attocube in developing new experimental setups has been really excellent!
