ET 2000 Series Silicon PIN Detector

Summary Box:

ET-2000 (4-variations 2030,2040,2060,2070) 2GHz Silicon (Si) biased photodetectors covering 300-1100nm. These PIN photodiodes from EOT are ideal for monitoring the output of Q-switched lasers; mode-locked lasers; and externally modulated CW lasers, with time domain and frequency response measurements

Description:

EOT's Silicon Photodetectors contain PIN photodiodes that utilize the photovoltaic effect to convert optical power into an electrical current. When terminated into 50Ω into an oscilloscope, the pulsewidth of a laser can be measured. When terminated into 50Ω into a spectrum analyzer, the frequency response of a laser can be measured. EOT's Silicon Photodetectors come with their own internal bias supply consisting of long-life lithium cells. Plugging a coaxial cable into the photodetector's BNC output connector and terminating into 50Ω at the oscilloscope or spectrum analyzer is all that is required for operation.
