Abstract
The detector has a pyroelectric element sandwiched between two electrodes which are transparent to the wavelength of radiation to be detected. The pyroelectric element is maintained in spaced relationship to the surface of a header by a pillar and by a lead of a microminiature package which is mounted on its back on the header surface. A second pyroelectric element can be similarly supported by another lead and another pillar. Electrical connections between the remaining leads and the posts of the header, and between the upper electrodes of the pyroelectric elements can be made with metal foil straps, thus eliminating the need for bonded wires.
