FC Bulkhead High Speed Photodetector, 1000-1600 nm Battery Biased InGaAs Detector, 2 GHz

The 818-BB-31 High Speed Photodetector consists of a free-space 1000 to 1600 nm biased InGaAs detector with a 0.10 mm active diameter and a <175 ps rise time. The detector utilizes an FC input connector for use with fiber optic signals. It includes a built-in bias supply consisting of two standard 3 V lithium cells (6V total bias) and a 50 ohm BNC connector output. The batteries are easily replaceable, and by disconnecting the detector from the oscilloscope input, when not in use, you can extend the lifetime of the batteries. It is equivalent to Coherent's Model ET-3010 (P/N 120-10050-0001).
InGaAs Free Space Detectors
The 818-BB-30, -31, and -35 consist of free-space, small and large area InGaAs detectors, with rise times ranging from 300 ps to 1.5 ns for covering the 1000-1600 nm wavelength range. Each unit includes a built-in bias supply consisting of standard 3 V lithium cells and a 50 ohm BNC connector output. The 818-BB-51 features an extended InGaAs photodetector with a wavelength range of 1475–2100 nm.
