iDus 401 Series

The Scientific Grade, 1024 x 127 deep depletion spectroscopy CCD camera is ideally suited to rapid analysis, multi-channel and low-light applications including fluorescence and Raman spectroscopy. The 401’s range of Front and Back Illuminated and Deep Depletion sensor options provide optimised performance from UV through Visible to Near IR.

  • Peak QE of 95%
  • TE cooling to -100°C
  • UltraVac™
  • Single window design
  • Fringe suppression technology


The USB2.0-based iDus series is a compact, yet feature-rich platform suitable for demanding spectroscopy applications such as low-light UV/NIR Photoluminence or Raman spectroscopy, as well as day-to-day routine laboratory operation and integration into industry-grade systems.

The iDus 401 boasts market-leading deep thermo-electric cooling to -100°C, complemented by Andor’s UltravacTM technology with its un-matched reliability track record in the scientific and industrial community. The iDus low-noise electronics allows seamless access to the best signal-to-noise ratio performance for the widest range of photon detection regimes.

Anti-fringing comes as standard on back-thinned & back-illuminated sensors for this 1024 x 127, 26 μm pixels array optimized for high dynamic range, high resolution and rapid data acquisition from Far UV to NIR.
