摘要
Heat mirror comprises at least one layer of highly conductive material thin enough to transmit visible light and thick enough to reflect IR and at least one dielectric layer having an index of refraction which increases in the IR range so that the dielectric causes phase matching in the visible range and mismatching in the IR range. The mirror is pref. an etalon of a dielectric layer sandwiched between layers of highly conductive material.
