Abstract

The invention relates to an optical detector (110) for an optical detection, in particular, of radiation within the infrared spectral range, specifically, with regard to sensing at least one optically conceivable property of an object (112). More particular, the optical detector (110) may be used for determining transmissivity, absorption, emission, reflectance, and/or a position of at least one object (112). Further, the invention relates to a method for manufacturing the optical detector (110) and to various uses of the optical detector (110). The optical detector (110) comprises —an optical filter (114) having at least a first surface (116) and a second surface (118), the second surface (118) being located oppositely with respect to the first surface (116), wherein the optical filter (114) is designed for allowing an incident light beam (120) received by the first surface (116) to pass through the optical filter (114) to the second surface (118), thereby generating a modified light beam (122) by modifying a spectral composition of the incident light beam (120); —a sensor layer (128) comprising a photosensitive material (130) being deposited on the second surface (118) of the opt…
