Midwave thermal infrared camera extended into the SWIR

High-detectivity and high-uniformity for accurate analysis

The Onca-MWIR-InSb uses advanced real-time image correction and is equipped with a state of the art 2D InSb array with 640 x 512 or 320 x 256 image resolution. The Onca-MWIR-InSb camera offers 14-bit images at various frame rates. Two speed versions are available: a standard video rate version and a high speed version.

All camera functions can be customized and all settings are stored in nonvolatile memory to enable optimized use. The Onca-MWIR-InSb is optimized for highly stable thermal imaging and thermography applications. Camera control and image acquisition are possible according to two standards: CameraLink and GigE Vision.

Benefits & features

  • Superframing
    Dynamic range enhancement technique combining several image frames with different integration times together in one "superframe"
  • Access to all camera settings
    Our standard Xeneth software allows for easy access to all camera settings
  • Microscopic objective lenses
    Microscope objective lenses (up to 4x magnification) are available for Onca cameras in the 3 to 5 um band
  • Simultaneously over GigE, CameraLink and analog out
    The onca camera can output images simultaneously over GigE and analog out, or CameraLink and analog out
  • User programmable filter wheel with multiple filters stacking
    The onca camera comes as standard with a filter wheel with 5 positions; in each position several filters can be mounted together
  • Temperature measurement accuracy within +/- 1°C or +/- 1%
    The onca camera can come with thermography as an option; temp measurement accuracy is +/- 1˚ C or +/- 1%
  • TrueThermal to stitch frames with different integration times
    A TrueThermal calibration allows for thermography with different integration time settings - this improves image quality and measurement accuracy for a variety of temperature ranges

Designed for use in

  • R&D
    Various scientific applications using infrared cameras in the 3 to 5 um range (or 1 to 5 um range)
  • Bio-Medical
    The MWIR are sensitive thermal cameras which can be used for temperature profiling of the human body
  • Thermography
    MWIR cameras can be used for accurate and stable temperature measurements (up to 2000degC)
  • Non-destructive testing
    Optical flash thermography, where the sample surface is heated by a brief pulse of heat/light. Mainly used for composites in aerospace industries
