Abstract
An apparatus and method for reading a bar code on an object includes a light diffusing cavity and a deflector. The deflector deflects and diffuses light from a light source which may be part of a bar code reader. Preferably the deflector deflects substantially all of the light from the reader, so that none of the light from the light source directly illuminates the bar code. Inner side wall surfaces of the light diffusing cavity redirect the deflected light to indirectly illuminate the bar code. Despite deflecting light from the light source, the deflector allows unhindered passage of light emanating from the bar code to a light detection system which may be part of the bar code reader.
