INFRAROT REFLEKTIERENDER OPTISCHER MEHRSCHICHT-KÖRPER |
摘要 |
An optical body comprising (a) a dielectric multilayer film having a reflecting band positioned to reflect infrared radiation of at least one polarization at an incident angle normal to the film, said reflecting band having a short wavelength bandedge lambda a0 and long wavelength bandedge lambda b0 at a normal incident angle, and a short wavelength bandedge lambda a theta and long wavelength bandedge lambda b theta at a maximum usage angle theta , wherein theta a theta is less than lambda a0 and lambda a0 is selectively positioned at a wavelength greater than about 700 nm; and (b) at least one component which at least partially absorbs or reflects radiation in the wavelength region between lambda a theta and lambda a0 at a normal angle of incidence. |
