The OP131 is a 935nm gallium arsenide (GaAs) Infrared LED mounted in a hermetically sealed package that provides an enhanced temperature range with a variety of power ranges. The housing also offers high power dissipation and superior protection for hostile environments. The device has a narrow beam with an inclusive angle at half power points of 18°. It has a broad irradiance pattern of 50° at half power points, providing relatively even illumination over a large area. This device is designed to efficiently operate with OP800, OP593, OP598 and OP599 phototransistors or the OP830 photodarlington.
