STENCIL PRINTERS AND THE LIKE, OPTICAL SYSTEMS THEREFOR, AND METHODS OF PRINTING AND INSPECTION

摘要

An optical system for use with printers and the like, printers incorporating such optical systems, methods for printing substrates and for inspection thereof are provided. The optical system may include one or more image capturing devices, and an image processing device for processing images captured by the image capturing devices to provide image data. The optical system is adapted for providing image data corresponding to at least two capture areas of substantially different dimensions on a common focusing plane or on different focusing planes of the optical system.
