Summary Box:
EOT's 2GHz amplified InGaAs sub-nanosecond photodetectors, ideal for monitoring the output of high repetition rate, externally modulated CW lasers.Description:
EOT’s <2GHz Amplified Photodetectors contain PIN photodiodes that utilize the photovoltaic effect to convert optical power into an electrical current and a fixed gain transimpedance amplifier allowing measurement of <1mW input powers. 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 <2GHz Amplified Photodetectors come with their own wall plug-in power supply. 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. The ET-3000A InGaAs detector for 800-1700nm.Specifications:
