Radial benders are used for the polarization analysis of the neutron beam scattered from the sample. Thin curved blades are arranged on a radius and form channel with an increasing channels width along the neutron propagation. The blades are coated with polarizing supermirror. The radial benders cover a large solid angle, e.g. 40° to 60° in the horizontal plane. The great benefits of these devices are: i) constant efficiency over time and ii) no maintenance.

Particular features are:

• angular coverage of 40° and more

• thin glass blades to minimize the loss of neutrons

• No "dark" areas due to structure of body
