Electro-Optics ET-3000A Amplified Photodetector

The Electro-Optics ET-3000A Amplified Photodetector is a high-sensitivity device designed for the detection of low-level optical signals. It integrates PIN photodiodes with a transimpedance amplifier to convert optical power into an electrical current. This photodetector is suitable for applications requiring the measurement of optical signals, such as in optical communications, laser detection, and spectroscopy, enabling tasks like measuring laser pulse width when terminated into an oscilloscope or frequency response when terminated into a spectrum analyzer. The device is characterized by its built-in amplifier, compact footprint, and a specified bandwidth, with options for different detector materials to suit various spectral ranges.
