High Speed Photodetector, 800-1750 nm Battery Biased InGaAs Detector, 2 GHz
Model: 818-BB-30
Product Series Overview
Biased Free Space Optical DetectorsThe 818-BB-30 High Speed InGaAs Detector consists of a free-space 800 to 1750 nm battery biased InGaAs photodiode with a 0.10 mm active diameter and a <175 ps rise time. A lens on the window, with an acceptance angle of 20°, is used to focus the beam on the photodiiode. 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-3000 (P/N 120-10034-0001).
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.
