    摘要: Embodiments of the present invention are directed to an apparatus for providing a low spring constant, pneumatic suspension using vacuum for the lens in a projection system. In one embodiment, a pneumatic suspension system for a load comprises a frame; and a body movably disposed in the frame and spaced from a side wall of the frame by a gap to define a chamber in the frame above the body, the body being configured to be connected to the load. The frame includes an outlet to draw a gas from the chamber to lower the pressure in the chamber with respect to an ambient pressure outside the frame. An air bearing is formed in the gap between the body and the side wall of the frame to provide non-contact between the body and the frame. The pressure in the chamber is sufficiently lower than the ambient pressure to produce a lift force to lift the body and the load connected thereto with respect to the frame.

    摘要: Methods, apparatus, and systems are disclosed for identifying force-ripple and/or side-forces in actuators used for moving a multiple-axis stage. The identified force-ripple and/or side-forces can be mapped, and maps of corresponding position-dependent compensation ratios useful for correcting same are obtained. The methods are especially useful for stages providing motion in at least one degree of freedom using multiple (redundant) actuators. In an exemplary method a stage member is displaced, using at least one selected actuator, multiple times over a set distance in the range of motion of the subject actuator(s). Each displacement has a predetermined trajectory and respective starting point in the range. For each displacement, respective section force-command(s) are extracted and normalized to a reference section force-command to define a section compensation-ratio. Multiple section compensation-ratios are assembled, as functions of displacement in the range, to provide a map of compensation ratios for the actuator(s) throughout the range.
