Claim Text:
1. An omnidirectional UV-IR reflector comprising: a multilayer stack having an average thickness between 0.5 and 10 microns and between four and thirteen layers, said between four and thirteen layers having at least two first index of refraction material layers H said between four and thirteen layers each having a predefined thickness of d wherein said multilayer stack when shined by light at incident angles between 0 to 45 degrees, has a first high reflectivity bandwidth with more than 50% reflectance of electromagnetic radiation having wavelengths less than about 400 nanometers, a second high reflectivity bandwidth with more than 80% reflectance of electromagnetic radiation having wavelengths greater than about 800 nanometers, and a low reflectivity bandwidth with less than 20% reflectance of electromagnetic radiation having wavelengths between about 400 nanometers to 800 nanometers.
