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.

Peak QE up to 95% - Visible-optimized ‘BVF’ & infrared-optimized ‘BR-DD’ model

Fringe suppression technology as standard - Fringing greatly eliminated (Deep-Depletion) or minimized (Back-Thinned ‘BVF‘)

TE cooling down to -100°C - Critical for elimination of dark current detection limit - no inconvenience associated with LN2.

Ultravac™ - Critical for sustained vacuum integrity and to maintain unequalled cooling and QE performance, year after year

Single UV-grade fused silica window - Best UV-NIR throughput performance, specific AR coating and wedge options available.

26 x 26 μm pixels - Optimized pixel format for high dynamic range and resolution.

Software-selectable pre-amplifier gain - Choice of best SNR performance of dynamic range at the touch of a button.

USB 2.0 connection - Ideal for laptop operation. Seamless operation alongside USB-based Shamrock spectrograph family

Compact and rugged platform - Ideal for OEM integration & laboratory setups.

Solis software for Spectroscopy - Comprehensive, user-friendly interface for simultaneous detector & spectrograph control.

Software Development Kit (SDK) - Ease of control integration into complex setups: Matlab, Labview, Visual Basic or C/C++.
