Abstract:
An integrated optics module for an optical scanning system that includes a scanning mechanism that generates a scan pattern from a laser beam is provided. The module includes an optics block, a laser mounted on the optics block, routing optics mounted on the optics block in the path of the laser beam emitted from the laser, a collection lens disposed on a surface of the optics block, and mounting fixtures configured to mount the optics module to the scanner housing in a fixed position. The routing optics are configured to route the laser beam through the collection lens toward the scanning mechanism when the module is mounted in the scanner system. If the laser beam routed through the collection lens is pre-aligned, no additional scanner system optical alignment is required when the optics module is mounted into the scanner housing.
