The DPD80 USB Photodetector

A digital USB photodetector allowing data to be streamed directly to your computer over USB 3.1, eliminating the need for a separate oscilloscope or spectrum analyzer.

DPD80 Digital Photodetector High Speed Low Noise USB streaming

Ultra-low Noise Measurements

With minimum noise equivalent powers of 3.0 pW / √ Hz  (760 nm) and 1.5 pW / √ Hz  (1550 nm) for the Si and InGaAs versions of photodiodes, the DPD80 USB Photodetector has lowest in-class noise floors of similar 100 MHz amplified detectors.

In addition to the 50Ω SMA analog output (DC - 100 MHz, -3dB), the integrated signal conditioning and digitization pathways optimize data collection and simplify measurement setups.

Simple Python code for the DPD80 photodetector

Fast Data Streaming to your Computer

The DPD80 photo­detector continuously streams data to your computer at a rate of 80 million samples / second (160 MB/s) using the USB 3.1 Gen 1 protocol. This digital connection from photo­detector to computer enables powerful digital signal processing abilities, while negating the need for an additional power supply.

Programming with Python, MATLAB™, and C/C++ libraries is supported allowing extensive customization of your data collection routines.

Included User Interface for Real-time Data Analysis

Our OpenGL accelerated user inter­face visualizes the incoming optical data in either the time domain or the frequ­ency domain, elim­inating the need for an external oscill­oscope, spectrum analyzer or analog to digital converter. Saving data and controlling your DPD80 USB photodetector is made simple with our interface.
