Large-area photodiode
A large-area quadrant silicon photodiode, the QD100-5T-COW is packaged in a design that allows mounting on plug-in PC boards. The windowless PIN quadrant detectors have a passivation layer that protects the photodiodes. Applications of the detector include use in laser-beam position detection, target acquisition, machine control, and encoder systems.
