RT-SWD (RT-USWD)
The RT-SWD vacuum shroud constitutes the standard solution for using a short working
distance objective at room temperature with a cold sample sitting on a stack of xyz
positioners with optional scanner and sample holder with optional electrical contacts.
It also features a 30 mm and 60 mm cage system threads and adapters.

Although the depth of focus decreases rapidly with increasing numerical aperture,
hence limiting the chromatic useful range, some people prefer to work at ultimately high
numerical apertures. This increases collection efficiency, and reduces integration time.
The attoDRY800 HV high vacuum objective shroud allows for integration of any standard
RMS (45 mm length) high vacuum compatible objective. The cold sample is sitting on a stack of
xyz positioners and optional scanner and sample holder with optional electrical contacts.
Customized
As previously described, the strength of the attoDRY800 cryo-optical table is that anything above
the cold plate can be customized. For example, we have integrated two LT-APO cold objectives for
transmission measurements. Due to the 8 side windows, the user can alternatively also observe
wide-angle scattering and collect light from the outside. Both objectives are carefully thermalized,
and 7 degrees of freedom given by xyz positioners allow for independent control of sample position
and both objective focal spots on the sample. Another customized shroud features 5 optical windows
with minimal working distance from all sides for room temperature objectives.
