The IB-C80-AIR slit system was initially developed for the SNS neutron facility, but since then, the system has also been used at synchrotron beamlines.

The system features four individually movable blades providing a large 80 mm x 80 mm opening with fully overlapping blades.

For standard synchrotron applications, we offer tungsten carbide blades. For neutron applications, B4C blades are a common choice.
