Overview

Our integrated circuits and reference designs help you create innovative spectrometer solutions.

Design requirements

Modern spectrometer systems often require:

  • High-performance measurements in a portable, low-cost form factor.
  • Optimized designs with DLP technology.
  • Seamless creation and displaying of high-speed pattern sequences through USB-based application programming interfaces (APIs).
  • Easy-to-use graphical user interface (GUI).
