SAX (Satellite per Astronomia X) is an Italian X-ray astronomy satellite with a Dutch contribution that will be placed in orbit in 1994. The prime scienctific object of SAX is to cover an energy bandwidth that ranges from 0.1 keV up to 200 keV. Among other instruments, SAX will consist of two X-ray Wide Field Cameras (WFCs) built by the Space Research Organization Netherlands at Utrecht. The WFCs are based on the coded mask principle; the reconstruction of the image takes place on ground. The field of view is 20 degrees square full width at half maximum (FWHM), the angular resolution 5 arcminutes (FWHM) and the energy band ranges from 1.8 to 30 keV with a resolution of 18% at 6 keV. The sensitive area is 200 sq cm at 6 keV. The mask pattern is based on a pseudo random array with 255 x 257 elements of 1 sq mm, 50% of which are transparent.
