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