When cryostats with optical windows need to be mounted and positioned, Holmarc's cryostat positioners can be considered. These XYZ three axis positioners are made for smooth and precise movements with heavy loads. Rolling contact bearings are used for all the three axis for play less and wobble free movements and positioning with rigidity and stability. A bracket having mounting holes for cryostat can be fixed to the Z axis as shown in the figure. Z axis is driven by worm gear assembly for effortless vertical positioning.
These positioners are available in motorized and manual version.
