Sometimes, the limited space around the beamlines or special requirements for the aperture size makes it difficult for a standard size slit to fit into a specific instrumentation. In that case, we are able to design and produce a customized solution which is developed from our standard slit systems – but with a rectangular housing.

Just as the classic IB-slit, the aperture is defined by 4 independently movable blades (2 blades for DEMI slit systems). The blades are in turn controlled by a high-precision guiding rail system and high-resolution stepping motors. In general, specifications and options often are very similar to our standard IB-slits.

Configuration and blade material are defined by the customer. If the slit system is used at an x-ray facility, the typical blades are 2, 4, 5 or 10 mm tungsten carbide blades -  e.g. with 0.5 degrees knife-edge, R16 cylindrical edge or 90 degree rectangular edge. For neutron instrumentation, we normally use Boron Carbide. 

If it is not possible to use a standard square system in your instrumentation (the most cost effective solution), you can check our already existing designs of rectangular slits systems here. Please contact for more information on a particular system. 

In our slit catalogue, you can have a quick overview of the large variety of JJ slit systems.
