The present invention relates to a sensor cover glass for covering photosensitive chips for generating electrical signals from an original image, as would be found for example in a digital scanner, copier, facsimile machine, or other digital imaging device or system. More specifically, the present invention relates to providing a sensor cover glass with an infrared filter material for blocking infrared light from reaching the photosensitive chips. This system is particularly applicable to color input imaging devices or systems.

Sensor cover glass with infrared filter

In a photosensitive chip suitable for full-color imaging, separate photosites on the chip correspond to different primary colors in an original image. Each primary-color photosite is filtered with a polyimide doped to a particular primary color. The red-filtering layer and the blue-filtering layer are left on the non-photosensitive portions of the main surface of the chip, and together serve as a non-reflective area which prevents stray reflections from the chip. The chip is further provided with a base layer of infrared-filtering polyimide.

Filter architecture for a photosensitive chip

A reflector tape assembly includes a reflective tape, a release liner, and a protective liner. The protective liner is attached to the reflective surface of the reflective tape. The protective liner protects the reflective surface of the reflective tape from scratches and other damage or contamination occurring during shipping, handling, and assembly. The protective liner is removed after the illuminator system is installed in the machine. The release liner protects the adhesive surface of the reflective tape during handling. The release liner ensures that the adhesive surface does not lose any tackiness or otherwise become damaged so as to have adhesion failure due to contamination during shipping and handling.
