The IB-C22-HV slit derives from the classic JJ X-Ray slit, IB-C30-HV, where space requires a smaller and more compact slit.

The aperture is defined by four independently movable and highly polished tungsten carbide blades. These blades are controlled by a high precision guiding rail system and stepping motors.

The blades can be installed in two configurations: Either providing a curved 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 roughness better than 25 nm RMS.

In its basic configuration, the IB-C22-HV slit is delivered with a flange-opening and tightening bolts to allow connection with KF-40 flanges.
