Claim 1
Independent Claim
184 words
A heat wave shielding lamination comprising a visible light transparent substrate and an overlying composite lamination consisting of at least one first electrically conductive layer formed of indium tin oxide and at least one second electrically conductive layer formed of In 2 O 3 arranged alternately on top of one another, said first and second layers having approximately the same refractive indexes in the visible light range in order to get good transmittance to visible light but having different refractive indexes in the infrared spectrum against which shielding is desired, said first layer having a thickness of about λ/4n A (where λ stands for the wavelength at the center of said infrared spectrum and n A stands for the refractive index at the wavelength λ) and said second layer having a thickness of about λ/4n B (where λ stands for the wavelength at the center of said infrared spectrum and n B stands for the refractive index at the wavelength λ), whereby said first and second layers together exhibit shielding effect against infrared rays in the infrared spectrum by interferential reflection of such rays.
