IB-C50-AIR for UHV

This is a modified version of our standard IB-C50-AIR. All parts and surfaces are suited for UHV operation (including microswitches, motors, wiring, connectors, guides and encoders). 

The IB-C50-AIR is a compact system but still spacious enough to house internal linear encoders (option). Our smallest system with this capability. Except for the additional space for internal encoders, the design is very similar to our classic IB-C30-AIR slit system: The aperture is defined by four independently movable highly polished tungsten carbide blades. The blades are in turn controlled by a high-precision guiding rail system and high-resolution stepping motors.

The standard 2 mm blades can be installed in two configurations: Either providing a curved polished surface of a radius of 16 mm or providing a knife-edge slope at 0.5 degrees. The standard blades are polished to obtain a RMS roughness better than 25 nm.

Without internal encoders, it is possible to reduce width in beam direction with 24 mm (2 mm blades).
