6 Axes LHe Cryostat Manipulator
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, R2 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 6 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, R2 and R3 rotations around the Z and Y axes. They can work in any orientation.
Options
• Full motorisation
