attoDRY800
cryo-optical table (closed-cycle)
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.
The revolutionary concept and design of the attoDRY800 present the
perfect solution to satisfy these demanding requirements: it consists of
an ultra low vibration cold breadboard platform which is fully integrated
into an optical table. The cryocooler assembly is located in the otherwise
unused space underneath. This unique design ensures a free workspace
and unobstructed optical access to the cold sample from all directions on
the optical table. Apochromatic objectives with high numerical aperture
(NA=0.81-0.95) can either be integrated into the cryostat, into the vacuum
shield, or put in close working distance next to the optical windows from
the outside. This ensures extremely low drifts and optimal collection
efficiency.

Being a closed-cycle cryostat, the attoDRY800 is the perfect replacement
for all helium flow cryostat setups, adding the huge advantage that
it requires no liquid cryogens and thus minimizing running costs. In
addition, a fully automa ted temperature control between 3.8 and 320 K
conveniently enables unattended long measurement cycles.
Most other off-the-shelf closed-cycle cryostats suffer from severe
vibrations at the sample location, which typically are in the range of
many microns. Thanks to our patented vibration isolation technique, the
residual vibrations on the cold plate of the attoDRY800 were measured to
be around 2.6 nm peak-to-peak (vertical direction) only. Hence, with the
attoDRY800 even extremely sensitive measurements are possible. Its cold
breadboard sample space is designed to host several of attocube’s patented
nanopositioners, as well as complete microscope or photonic probe station
solutions.
