IB-C50-AIR

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

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

Thermocouples for each blade

IB-C50-AIR with non-magnetic options are available (including non-magnetic guides).

Blade options: 5, 10 mm, other blade materials
Motors: Custom high-resolution stepping motors, including IMS motors
Encoders: Back-axle rotary encoders or Linear Renishaw encoders (absolute or incremental)
