Versatile SWIR T2SL camera with response up to 2.35 μm

Superior performance for reliable research

The Xeva-2.35-320 is a compact digital camera operating a T2SL detector array for imaging in the 1.0 to 2.35 μm wavelength range. The camera features a resolution of 320 x 256 pixels with a 30 μm pixel pitch. It outputs 14-bit data and comes in a 100 Hz (USB 2.0)
or 350 Hz (CameraLink) version. 

The camera interfaces to a PC via standard USB 2.0 or CameraLink. Each camera is delivered with a Graphical User Interface (GUI) Xeneth, which offers direct access to various camera settings such as exposure time and operating temperature. The camera allows for exposure times from 1 μs to 60 ms in high dynamic range mode (with TE4 cooling).

Through its advanced thermomechanical design, the Xeva-2.35-320 achieves excellent performance levels using a TE4-cooled device operating down to 203K.

    The Xeva-2.35-320 is a very small TE4 cooled T2SL camera with low dark current and response up to 2.35 µm
  • High speed SWIR imaging up to 2.35 µm
    The Xeva-2.35-320 allows for high frame rate imaging up to 344 full frames per second - in a reduced window of interest, even higher frame rates are possible
  • Scientific image recording and analysis
    Our standard Xeneth GUI allows for easy recording of images in full (bit) resolution
  • CameraLink and triggering for high speed imaging
    CameraLink interface is suitable for high datarates - triggering can be used for synchronisation at high frame rates

Designed for use in

  • Art inspection
    SWIR photons can penetrate through paint, hence underdrawings can be investigated
  • Hyperspectral imaging
    Combination of spectral imaging and 2D imaging. Our SWIR camera are used for hyperspectral SWIR imaging
  • 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
  • Semiconductor inspection
    SWIR cameras are able to see through silicon
  • High temperature thermography (in the 300˚ C- 1200˚ C range or up to 2000˚ C)
    SWIR cameras can be used for thermal imaging in the temperature range above 300 degrees C
