ABSTRACT:
An all-polymeric cold mirror which reflects visible wavelengths while transmitting a substantial portion of infrared wavelengths is provided. The mirror includes a sufficient number of alternating layers of at least first and second diverse polymeric materials such that at least 50% of peak reflecting visible light of a wavelength of between about 380-680 nm incident on the mirror is reflected and at least 50% of infrared light between about 680-2000 nm is transmitted or absorbed. The mirror may be designed so that it either reflects or absorbs ultraviolet light.
