  • InGaAs photodiode


The Resolved Instruments DPD80 USB Photodetector is a high-speed and low-noise photodetector. It is optimized for measurements ranging from 1 to 100 MHz.

The DPD80 is powered by a USB type-C connector, provides 80 kV/A amplification of the photodiode current, and outputs its voltage signal to a SMA port. It uses high-quality photodiodes from Hamamatsu and the latest in low-noise current amplifiers. This results in the lowest in-class noise-floors.

The DPD80 has an integrated 14-bit 80 MegaSample / second analog-to-digital converter. This enables signal streaming in real-time to a PC over USB. This eliminates the need for separate amplifiers, analog-to-digital converters, oscilloscopes, and spectrum analyzers. Resolved Instruments also programmed data collection and automation tools using Python, MATLAB, and C so that you can work in your preferred programming language.

Each DPD80 Photodetector comes with a Certificate of Calibration which shows that your photodetector was individually calibrated before shipment.
