Silicon Photodetectors Data Sheet
Silicon Photodetectors
EOT’s Silicon 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 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 50 Ω at the oscilloscope or spectrum analyzer is all that is required for operation.
Applications:
· Monitoring the output of Q-switched lasers
· Monitoring the output of mode-locked lasers
· Monitoring the output of externally modulated CW lasers
· Time domain and frequency response measurements
Features:
· Silicon photodetectors can be ordered with optional wall plug-in power supply
