Abstract
An infrared radiation (IR) detector includes a cold shield consisting of (a) a light shielding portion having a substrate made of an infrared transmissive material, an infrared absorbing layer formed on one surface of the substrate, a dielectric layer formed on the infrared absorbing layer and an infrared reflecting layer formed on the dielectric layer, and (b) an opening portion consisting of a substrate made of an infrared transmissive material and a dielectric layer formed on the one surface of the substrate. The substrate and the dielectric layer are connected and generally continuous between the light shielding portion and the opening portion. The IR detector also includes an infrared detector array having a detective area arranged just below the opening portion of the cold shield.
