Abstract
A solid state photodiode is configured to have its rear face light responsive and is electrically connected to a lead frame or flexible carrier with conductor traces, which includes an aperture to allow light to impact the rear face. A photodiode with light responsive front and rear faces, with or without filters, permits various applications to be implemented relatively inexpensively when compared to prior art systems.
