Basic (Standard Shroud)
basic vacuum shroud for use with a room temperature objective
By default, and if no other option is chosen, the attoDRY800 optical cryostat is delivered with the basic vacuum shroud. It constitutes a geometry which is almost identical to what hundreds of labs worldwide have been using for decades with their flow cryostats. Designed for room temperature optics, the sample sits on a manually adjustable holder at a typ. minimum working distance of about 3.5 mm. In addition to 88x M6 breadboard mounting holes on a 12.5 mm grid, it also features a 30 mm and 60 mm cage system threads and adapters.
