InGaAs amplified photodetector 800-1700nm (140MHz )

InGaAs amplified photodetector 800-1700nm (140MHz )

Indium Gallium Arsenide (InGaAs ) photodetector is a rated bandwidth, with the fixed gain photodetector to detect optical signals. The optical signal is input from the photoelectric sensor sensing surface and output in the form of voltage through BNC. This product can measure optical signals in the wavelength range of 800nm to 1700nm. For specific performance parameter data, please refer to the appendix table. The Idealphotonicx photodetector housing has a mounting hole with an imperial 1/4"-20 thread, which can be easily installed and fixed. The housing also comes with two different sizes of threaded rings, which are suitable for industrial applications and scientific research applications respectively, and can be easily adapted to external optical components such as filters, attenuators, lenses, FC fiber adapters, etc. The product includes a plastic dust cover. For specific installation, please refer to Chapter 3. Each photodetector is equipped with a DC linear power supply with an output of ±9V. The input rated voltage of the DC power supply is 220VAC/50HZ

Product features：Low noise, less than ±1mV、 Small overshoot, overshoot voltage less than 2.5%、 Gain stability: gain error is less than 1%、 Dark bias voltage output noise: less than 1mV (rms)

Part Number：--

Application area：Display panel inspection 、LED lighting stroboscopic analysis 、Measurement of flashing frequency and power of toy lights 、 Gas analysis
