Abstract
An optical sensor and filter assembly is provided and includes an optical sensor, a filter and a mounting structure. The optical sensor includes a detector layer having first and second opposed faces and a read-out integrated circuit (ROIC) to which the first face of the detector layer is hybridized. The filter permits passage of one or more wavelength bands of interest of incident light toward the optical sensor and the mounting structure directly hybridizes the filter to the second face of the detector layer.
