Xeva-1.7-320 VisNIR

Advanced research in SWIR imaging

Cooled and stable for excellent VisNIR image quality research

In one compact housing, the Xeva-1.7-320 VisNIR digital camera combines a thermo-electrically cooled InGaAs detector head and the control and communication electronics.

The Xeva-1.7-320 VisNIR unit is available with standard (up to 1.7 μm) InGaAs detector arrays and comes in various speed versions: 60 Hz, 100 Hz and 350 Hz. It allows you to choose the most suitable detectorcamera configuration for your specific application. The camera head interfaces to a PC via standard USB 2.0 or CameraLink.

Each camera is delivered with a graphical user interface Xeneth, which offers direct access to various camera settings such as exposure time and operating temperature. The software tools include two-point uniformity correction and bad pixel replacement.

Benefits & features

  • Spectrometer compatible
    These cameras have mounting holes for spectrographs, making them suitable for (hyper)spectral imaging applications
  • Thermal imaging of hot objects
    SWIR cameras are ideal for thermal imaging of hot metals (> 300 degC)
  • High sensitivity for low-light conditions
    Low noise, low dark current detectors for extended integration times
  • Extending SWIR imaging to the visible
    VISNIR or visible enhanced InGaAs sensors for extended response from 500 to 1700 nm
  • Cooled operation for low light-level imaging
    A cooled SWIR detector has lower dark current and allows for longer integration times
  • Flexible programming in an open architecture
    SDK (Software Developing Kit) available for all cameras - samples available for C++, LabView, Linux…
  • CameraLink and triggering for high speed imaging
    CameraLink interface is suitable for high datarates - triggering can be used for synchronisation at high frame rates
  • Extended coverage from SWIR into the visible range
    VISNIR or visible enhanced InGaAs sensors for extended response from 500 to 1700 nm

Designed for use in

  • Art inspection
    SWIR photons can penetrate through paint, hence underdrawings can be investigated
  • Food inspection
    Bruises on food can be detected due to the higher moisture contect which will appear darker in the SWIR images
  • R&D (SWIR range)
    SWIR range is a relatively unexplored range and hence providing much research opportunities
  • Laser beam profiling
    Laser beam analysis for infrared lasers at, e.g., 1064, 1300 and 1550 nm
  • Hyperspectral imaging
    Combination of spectral imaging and 2D imaging. Our SWIR camera are used for hyperspectral SWIR imaging
  • Semiconductor inspection
    SWIR cameras are able to see through silicon
  • Solar cell inspection EL/PL
    Inspection techniques for crack inspection or efficiency mapping based on electroluminescence or photoluminescence
