The 420’s range of Front (Open Electrode) 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
  • 26 x 26 μm pixel size

Workhorse laboratory and OEM CCD platform

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 420 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.

This 1024 x 255 pixel matrix boasts a range of far UV and VIS-optimized back-thinned sensors & NIR-optimized back-illuminated (‘fringe-suppressed’) sensor options. Its, 26 x 26 μm pixel size is optimized for high dynamic range and high resolution, while its 6.6 mm height is ideally suited to multi-track spectroscopy.
