OPTICAL SENSOR AND DETECTOR FOR AN OPTICAL DETECTION

An optical sensor (110) comprises a substrate (124) attached to a circuit carrier device (142), a layer (112) of at least one photoconductive material (114) which is directly or indirectly applied to the substrate (124), at least two individual electrical contacts (136, 136') contacting the layer (112) of the photoconductive material (114), and a cover (116) covering accessible surfaces of the layer (112) of the photoconductive material (114) and of the substrate (124), wherein the cover (116) is an amorphous cover which comprises at least one metal-containing compound (120), wherein at least one of the substrate (124) and the cover (116) is optically transparent within a wavelength range. A manufacturing method for the optical sensor (110) is also provided. The optical sensor (110) can, thus, be supplied as a non-bulky hermetic package which provides an increased degree of protection against possible degradation by humidity and/or oxygen over long terms. Further, the optical sensor (110) may be easily manufa
