RT free-beam/5-sides

vacuum shroud with medium WD for RT objectives from 5 sides

This vacuum shroud features 5 optical windows for simultaneous low working distance from 3 sides or more. The typ. minimum working distance from the top is 11 mm, from the side ports it is 16 mm with the sample still centered; the actual value depends on the position of the region of interest on the sample itself, its position on the sample holder, and the travel position of the nanopositioners. The shroud is compatible with a set of xyz positioners, and typically hosts a dedicated sample holder specifically designed for this configuration. The shroud is compatible with the 60 mm cage system for mounting optical components on the outside, and features the standard feedthrough ring compatible with all usual optional feedthrough types.
