Request InfoOptek Technology, Industrial Sensing & ControlOptek Technology has developed a series of negative-positive-negative silicon phototransistors in 1206-chip packages. The OP520/OP521 series miniaturized surface-mount devices perform infrared detection in sensing applications, with response times of 15 µs and peak response to 880-nm light. Both devices are packaged with a flat molded lens. The OP520 has an opaque lens to shield it from ambient light, and the OP521 has a water-clear one for a wider response range. Electrical performance is characterized at collector-emitter voltage of 30 V, emitter-collector voltage of 5 V, collector current...See full productRelated content from Photonics MediaWEBINARSPhotonics.com 6/22/2023Revolutionizing Infrared Detection: Five Key Advantages of InAs and InAsSb-Based Detectors for Unmatched PerformanceLukasz Kubiszyn of VIGO Photonics covers many of the key advancements in InAs and InAsSb based detection for mid-wave IR and long-wave IR for applications spanning from environmental monitoring to...Photonics.com 1/18/2018Fiberguide RARe Motheye Fiber: Random Anti-Reflective (RARe) Nanostructures on Optical Fibers as Replacement for AR CoatingsAnti-reflective (AR) coatings are now entering their second century and have remained virtually unchanged throughout their life.
