It covers 380-1100 nm with a 1.5 GHz bandwidth and a rise \/ fall time of \u0026lt;270 ps\/\u0026lt;270 ps, converting optical power into photocurrent through the photovoltaic effect. An internal long-life lithium bias supply is built in, so the detector needs no external bias: connect a coaxial cable from the BNC output to a 50 Ω termination at an oscilloscope or spectrum analyser and the unit is ready to measure laser pulse width and temporal response.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eQ-switched laser output monitoring\u003c\/li\u003e\n  \u003cli\u003eMode-locked laser output monitoring\u003c\/li\u003e\n  \u003cli\u003eExternally modulated CW laser output monitoring\u003c\/li\u003e\n  \u003cli\u003eTime-domain and frequency-domain response measurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConstruction \u0026amp; Performance\u003c\/h3\u003e\n\u003cp\u003eThe 35 × 35 × 55 mm housing carries a 0.2 mm effective detection diameter with a 45° acceptance angle and 1 pA dark current; response sensitivity is 0.4A\/W@700 nm.

Always terminate the output into 50 Ω when measuring fast pulses, and avoid exceeding the specified maximum optical input. Remove the bias battery if the detector will be stored for an extended period, and keep the unit in a clean, dry environment away from direct sunlight and condensation.\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":48961218085018,"sku":"BIM-7801-02","price":0.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/high-speed-biased-photodetectors-detector-head_02b538f2-94cf-482a-b78d-f28ac6c8d044.png?v=1786004486","url":"https:\/\/waveqvanta.com\/products\/high-speed-biased-photodetectors-bim-7801-02","provider":"WaveQuanta","version":"1.0","type":"link"}
