    摘要: In one embodiment an ink cartridge includes: a housing defining an ink holding chamber; and a molded plastic prism having a light reflecting surface exposed to an interior of the ink holding chamber, a cavity therein for relieving strain in the prism as the prism cools from molding, and a textured surface defining one wall of the cavity. In another embodiment, an ink cartridge includes: an ink holding chamber; and a prism having: a base through which light may enter the prism; a reflecting surface exposed to an interior of the ink holding chamber, the reflecting surface oriented relative to the base such that light entering the prism through the base is reflected off the reflecting surface at varying levels depending on a refractive index of an environmental medium surrounding the reflecting surface; and a cavity having a light-scattering surface therein.
