Low Speed Photodetectors
Low Speed Photodetectors
產品名稱 : Low Speed Photodetectors
產品說明 :
EOT’s Low 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 Low Speed 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.
