ABSTRACT A method of manufacturing an infra-red detector in which a printed form of lead-out contact pattern is applied to the or each infra-red sensitive element. A detector element of infra-red sensitive material is provided having at one major side at least one active surface area defined between spaced contact layers which extend over oppositely located curved edges of the element at said side. The element is adhered via the opposite major side to an insulating substrate having a contact pattern provided thereon. Electrically conductive material is deposited to forming interconnections between the contact layers on the element and adjacently situated end portions of lead-out conductors of the contact pattern. Specification describes a method of replacing defective elements in an array and forming new inter- connections thereto without necessity of using special masking. -44-
