The IB-C30-AIR is the classic JJ X-Ray slit Type 3. 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.

This slit system is rugged and durable, often providing our customers many years of reliable and repeatable operation.

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

Common options include Adaptor for X95 profiles, IMS intelligent motors, back-axle encoders, and various blade shapes.
