The system 3002.70M is a compact motorised vacuum slit screen with an overall length of just 160 mm.
Each of the four blades is driven by a step motor.
Usual applications are in experimental set-ups with extremely limited space and the additional requirement of guiding the beam in vacuum or a defined atmosphere. Each of the four blades can be adjusted individually and with high precision by step motors.
Four step motors of extremely low height mounted on the outside of the housing drive the mechanism via vacuum manipulators. The maximum aperture size is 12mm x 12mm.
The slit screen is equipped with limit switches to prevent collision and mechanical damage. The aperture has a KF-flange on both sides, as well as an additional connection for the vacuum pump.
The KF-flanges can be used for simple adaption to other optical components such as HUBER tube slit screens, HUBER vacuum polarisation analysers or Oxford-Danfysik detectors.
The slit screen is optionally mounted on a X95-Profile or a HUBER prism carriage. Thus it can be easily interchanged or mated with other beam line components.
