5 Axes LHe Cryostat Manipulator (open cycle, 4.8K) [project 330]
Description
The Manipulator with Helium Cryostat is a versatile, open cycle system that has many applications in ultra-high vacuum research. The manipulator is a high precision, high rigidity, UHV specimen manipulator of modular construction, suitable for a range of X, Y and Z linear motions and R1 and R3 rotations. The modular construction means that the specification can be upgraded or modified by the addition or replacement of well-defined modules.
Application
The 5 Axes Manipulators are used for manipulating sample holders and scientific tools with respect to a sample’s position. These manipulators, when combined with sample holders, allow precise placement and manipulation of samples in UHV environments. The manipulators themselves move the sample in three orthogonal axes, X, Y, and Z, while the rotary drives provide R1 and R3 rotations around the Z and Y axes. They can work in any orientation.
Options
• Full motorisation
• Full software control
