IB-C50-AIR

The IB-C50-AIR is a compact system but still spacious enough to house intermal linear encoders. 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.

If a slightly larger aperture is needed, the IB-C50-AIR can easily be modified to an IB-C60-AIR (aperture size of 60 mm x 60 mm).

Please notice: IB-C50-AIR in the picture are shown with encoder option.
