Abstract

The present invention provides an optics module for a scanning device such as a portable scanner. The optics module includes an illumination source and guide that transmits light through an optical window of the scanning device casing before reflecting off of the object to be scanned. The reflected light from the object travels back through the optical window and a lens before reaching a photosensor for evaluation by an associated microprocessor. The optical window of the scanning device provides a recessed portion in the scanning device casing. The recessed portion of the window is formed using the functional components of the optics module to eliminate a piece of glass typically used within the optical window that can be easily scratched or broken and provides a loss during the illumination process. By using the functional components of the optics module to form the recessed optical window, manufacturing costs to secure and replace a typical glass window contained therein can be eliminated, size of the optics module is reduced, and any contaminates that gather around the optics module can be easily removed by the user.
