Proven Low Vibrations attoDRY800 selected measurements
Vibration measurements on cold plate of attoDRY800
The interferometric measurements to the left show vertical & horizontal displacement data measured directly on the cold plate of the attoDRY800. The peak-to-peak vibrations in vertical direction are around 3 nm( 4 nm), while in lateral direction they are around 2 nm( 17 nm) in a bandwidth of 200 Hz( 1500 Hz). This very efficient and unique low vibration design even allows for very sensitive optical measurements such as optical probe stations or high resolution optical spectroscopy on nanostructures.
Direction
Peak-to-Peak @ 200 Hz( 1500 Hz)
RMS @ 200 Hz( 1500 Hz)
vertical 3 nm( 4 nm) 1.0 nm( 1.1 nm) horizontal 2 nm( 17 nm) 0.6 nm( 2.1 nm)
The FFT of the data above is shown to the left as well for both directions, vertical and horizontal respectively, at a bandwidth of 1500 Hz. The dashed line at 1 pm indicates the noise floor of the interferometer.

Dr. Heindel
Our group is working on quantum optics experiments exploiting deterministic quantum light sources based on semiconductor quantum dots. The two attoDRY800 systems will be used to probe the mututal two-photon interference of remote quantum emitter located in both cryostats. We are keen on the exciting experiments possible with these very stable cryostat systems.
