IB-C30-UHV

For monochromatic applications, IB-C30-UHV is offered as a reliable and well-proven UHV compatible slit system with many of the same design features as our well-known air and vacuum slit systems.

As the air and vacuum IB-slits, the aperture in the UHV version is defined by four independently movable and highly polished tungsten carbide blades. These blades are controlled by a high-precision in-vacuum guiding rail system. The guides are positioned close to the blades giving the shortest distance from the guide to the blade.

To avoid issues of UHV contamination and overheating of the motors, the high-resolution stepping motors are positioned outside vacuum, and all motions are established via magnetically coupled feed-throughs.

In its basic configuration, IB-C30-UHV slit is delivered with a flange-opening to allow connection with a CF-100 flange. Other flanges are also available upon request.

We recommend the option with internal linear UHV compatible encoders in order to obtain precise knowledge about the actual blade position.
