Abstract
A scanner for scanning a one or two-dimensional bar code symbology is provided that effectively prevents condensation from forming on the protective window. The scanner comprises a housing having an electro-optical element and a window permitting the electro-optical element to collect reflected light therethrough. A heating element is coupled to at least a peripheral portion of the inner surface of the window. Application of an electrical current to the heating element heats the window and precludes condensation from forming on the inner surface of the window. The heating element may further comprise a resistive element having an adhesive layer permitting attachment to the inner surface of the window. The heating element would be further compatible with operation of conventional electro-optical elements, such as a charge coupled device or a laser.
