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 presents 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 via 4 side and 1 top window.
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 automated temperature control
between 3.8 and 320 K conveniently enables unattended long
measurement cycles.
While most other off-the-shelf closed-cycle cryostats suffer from severe
vibrations at the sample location, during the development process of
the attoDRY800 special attention was given to keep the vibration level
via a patented vibration isolation technology smaller than 1 nm (RMS).
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.
