1. A scanner and/or copier comprising:
at least one light source; at least one first surface mirror for reflecting light from, directly or indirectly, a document in the scanner and/or copier; wherein the first surface mirror includes: (a) a glass substrate; (b) a reflective layer comprising aluminum, an aluminum alloy, silver, and/or a silver alloy; (c) a first dielectric layer comprising (i) an oxide, nitride and/or oxynitride of silicon, and/or (ii) an oxide of aluminum, wherein the reflective layer is located between at least the glass substrate and the first dielectric layer; and (d) a layer comprising (i) an oxide of titanium, (ii) an oxide of niobium, (iii) a nitride and/or oxynitride of silicon, and/or (iv) ITO, wherein the first dielectric layer is located between at least the reflective layer and the layer comprising (i) an oxide of titanium, (ii) an oxide of niobium, (iii) a nitride and/or oxynitride of silicon, and/or (iv) ITO; and wherein a difference between p-polarization reflectance and s-polarization reflectance of the first surface mirror measured at about 780 nm, for incoming light incident at substantially all angles from 0 to 60 degrees, is from 0 to 3%.
