A balanced USB photodetector that internally digitizes your data, allowing data to be streamed directly to your computer over USB 3.1, eliminating the need for a separate oscilloscope or spectrum analyzer.
With low minimum noise equivalent powers of 4.5 pW / √ Hz and 2.5 pW / √ Hz for the visible and infrared versions of the DPD80 balanced photodetector can improve your signal to noise. Additionally, the immediate internal amplification and digitization eliminates signal degradation and noise pickup from coaxial cables.
The DPD80 balanced photodetector can continuously stream data to your computer at a sample rate of 80 megasamples / second using USB 3.1. This digital connection from photodetector to computer simplifies experimental setups and powers the device so that it doesn't require a separate power supply. We also support Python, MATLAB, and C libraries allowing you to automate your data collection.
Our touch-screen compatible user interface allows you to view 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 balanced photodetector is made simple with our interface.
