<p>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 μa0 and long wavelength bandedge μb0 at a normal incident angle, and a short wavelength bandedge μaυ and long wavelength bandedge μbυ at a maximum usage angle υ, wherein μaυ is less than μa0 and μa0 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 μaυ and μa0 at a normal angle of incidence.</p> |
