Detector selection guide

Home/Resources/Detector resources/Detector selection guide

The table below can be used to identify which type of linear array detector best suits your spectroscopy application based on:

  • Wavelength range
  • High sensitivity versus large dynamic range/high SNR
  • Integration time

For wavelengths below 1100 nm (UV, VIS, NIR), you should use silicon detectors (CCD or CMOS/NMOS), and for wavelengths above 1100 nm, you should choose InGaAs detectors.

For silicon detectors, choose CMOS/CCD’s when you have low light levels and therefore need high sensitivity, and choose NMOS, when you have higher light levels and want the best signal-to-noise ratio and/or dynamic range.

Choose cooled detectors, when your application requires long integration times.
