SOLAR HEAT CONTROL TYPE DURABLE THIN-FILM COATING HAVING LOW EMISSIVITY

摘要

PURPOSE: To obtain a durable thin-film interference filter having low emissivity and high visible light transmittance. ;CONSTITUTION: This thin-film interference filter successively includes the following layers: A transparent substrate ; a substantially transparent first dielectric layer; a first metallic precoating layer; a partial reflection metallic layer; a second metallic precoating layer; and a substantially transparent second dielectric layer. The first metallic precoating layer contains nickel and chromium or chromium nitride and the second metallic precoating layer includes nickel and chromium nitride.;COPYRIGHT: (C)1994,JPO
