with maximum opening of 5 mm. With an aperture of 1 mm the slit can be positioned asymmetrically by ± 2.5 mm from the optical axis. The slits are standard made from aluminum alloy or stainless steel. For high energy radiation, slits up to 3 mm thickness made from tungsten, titanium or stainless steel are optionally available. All slits are calibrated in pairs and lobed. High-precision, selected preloaded recirculating ball screws guarantee a parallel opening and closing of the slits. To avoid collision or damage, the slits are protected by a safety clutch and a limit switch. By combining two single slits, one cross slit can be easily configured. Slit jaws are not included in the standard product and must be ordered separately. The slit yaws are listed on page 7.030.
