ET-5000 Series High Speed Detector


The ET5000 series from EOT are high speed indium gallium arsenide (InGaAs) detectors offering responsivity from 1475nm to 2100nm with a rise and fall time of <50ps. These detectors are ideally suited to monitoring free space or fiber thulium (Tm) and holmium (Ho) lasers.

With a responsivity of 1475nm to 2100nm these high speed detectors are ideally suited to pulse width measurement of sub-nanosecond lasers and monitoring of Tm and Ho lasers. The ET-5000 series feature a 40µm active area, bandwidth of >12.5GHz and a rise and fall time of <30ps.
