Abstract: A robotic system automatically aligns, and/or tests alignment of, a lens to a digital camera or other workpiece. The system includes an optical target, an intermediate lens and a plurality of collimators peripheral to the intermediate lens to accommodate a wide range of fields of view of the workpieces, without requiring changes in equipment hardware. When manufacturing or testing a workpiece with a relatively narrow field of view, the entire field of view of the workpiece can be filled with a view of the target through the intermediate lens, and the collimators need not be used. However, when manufacturing or testing a camera having a relatively large field of view, the intermediate lens is used to fill a central portion of the field of view with an image of the target, and the collimators are used to fill a remaining portion of the field of view with images of reticles.

Abstract: A parallel DAC topology reduces systematic linearity errors by offsetting the digital codes inputted to the individual DACs from one another. Linearity errors that would normally add together are thus reduced.
