IB-C30-HV

IB-C30-HV is our worldwide top-seller – also known as Type 3 Vacuum JJ X-Ray slit. The system is suitable for vacuum applications, where O-ring sealing is sufficient.

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

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

In its basic configuration, the IB-C30-HV slit is delivered with a flange-opening and tightening bolts to allow connection with KF-40 flanges.
