    • 320-1100nm Silicon Amplified Photodetector (DC-200kHz)

    The PDAM20A6B4G-InGaAS photodetector is a fixed-gain photodetector with a rated bandwidth, used to detect optical signals. The optical signal is input from the photoelectric sensor sensing surface and output in the form of voltage through the 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 photodetector housing has a mounting hole with a British 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.

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