System3 is a modular camera system that can be operated in both, line- and point-collimation mode on conventional sealed-tube or rotating-anode generators. For measurements on isotropic, unoriented samples such as dilute macromolecular solutions, nanopowders, polymers, or ceramic materials, line collimation X-ray optics are a viable and economical alternative to point-focussing optics. Reliable software tools are available for the necessary corrections of the scattering curves (desmearing).
