attoDRY800xs
compact optical cryostat
most compact standalone optical cryostat
fits in every laboratory
cold plate integrated into optical breadboard
obstruction-free work space & optical access
fully customizable vacuum shrouds
can be customized to almost every need
With the attoDRY800xs optical cryostat, attocube has taken the revolutionary concept of the attoDRY800 to the next level: many researchers want to set up quantum optics experiments at cryogenic temperatures, but don‘t have room for a(nother) conventional optical table, or big cryostats which occupy several m3 of precious lab space.
The attoDRY800xs overcomes this limitation, being the most compact platform ever for quantum optics experiments: a customizable cryogenic shroud, equipped with the optical setup that you desire, integrated into an optical breadboard. The result is the first standalone optical cryostat ever, where the cold sample space is perfectly embedded into an obstruction-free workspace.
All this in less than 17‘‘ x 28‘‘, while preserving all key advantages of the original attoDRY800, such as a similar low vibration performance, versatility through customizable vacuum shrouds adopted to the needs of your experiment, and automated temperature control, gas handling and remote control.
Therefore, the attoDRY800xs can enable to set up a self-contained experiment directly on its optical breadboard, or it can be placed adjacent to existing larger optical tables with fiber coupling between the optical elements.

Vacuum Shrouds
Anticipating typical configurations, we have designed several standard vacuum shrouds and cold shields for the attoDRY800/800xs optical cryostat, that are intended for certain types of positioners, sample holders, working distances and objectives. These options constitute an economic pre-configured set of components that give the user a head start for his research with optics at low and variable temperatures.
The vacuum shroud can have an almost arbitrary shape depending on the experimental needs of each user. We distinguish between standard configurations, which cover the most typical applications, and fully customized configurations.

Vibration measurements on cold plate of attoDRY800xs
Thanks to a brilliant design, the renowned ultra-low vibration mechanism of the attoDRY800 has successfully migrated into a compact version. As depicted by the plot on the left, the interferometric measurements on the attoDRY800xs cold plate show peak-to-peak vibrations in vertical direction which are less than 2 nm (3 nm), while in lateral direction they are inferior to 10 nm (40 nm), in a bandwidth of 200 Hz (1500 Hz).
This revolutionary concept allows for very sensitive optical measurements even when the lab space becomes a constraint.
| Direction |
Peak-to-Peak |
RMS |
| vertical | 2 nm (3 nm) | 0.8 nm (0.8 nm) |
| horizontal | 10 nm (40 nm) | 1.7 nm (2.5 nm) |
