Spectrometer Electronics

The function of our spectrometer electronics is to convert the analogue video signal from the diode-array detector to a robust digital signal that can be read out over a standard interface (like USB or SPI).

We offer four options for spectrometer electronics for most of our spectrometersSpectrometer electronics overview

  • DISB – digital image sensor board with fast SPI interface
  • VersaPic – low speed USB controller with on-board processing
  • Andor iVac camera – deeply cooled and highly sensitive
  • No electronics – if you want to build your own electronics

The table below highlights the main features of our electronics offerings and lists the detectors that are supported by the various electronics options..
