An image sensing device is disclosed having a die formed with an array of photosensing sites and a structure of optical material having infrared absorbing characteristics formed over the photosensing sites. An embodiment is disclosed in which the structure of optical material having infrared absorbing characteristics is formed as an array of microlenses for directing visible image light onto the photosensing sites and at the same time filtering out infrared wavelengths that interfere with image capture. Alternatively, the structure may be designed to filter out other ranges of wavelengths outside of the visible spectrum.
