The OP280 series of infrared emitters and the OP580 series of matching silicon photo sensors from OPTEK Technology (Carrollton, TX) were named PTB Product of the Month for January. The OP280 emitter series consists of three standard devices: the OP180 940-nm infrared emitter, the OP280 880-nm infrared emitter, and the OP280K 890-nm infrared emitter; and the OP280PS 850-nm point source infrared emitter and the OP280V 850-nm vertical cavity surface emitting laser (VCSEL) device. The OP580 series of sensors consists of the OP580 phototransistor, the OP580PR silicon photodarlington, and the OP580RB silicon phototransistor with an integrated base-emitter resistor.
