World’s fastest InGaAs camera

New 800 Hz version

The Cheetah-640-CL camera is the fastest InGaAs infrared camera in the world. The camera has been designed for applications where high speed imaging matters. Whether for adaptive optics, spectral analysis in the SWIR band, tracking of fast and hot objects, electro-coalescence, etc.

This unit is equipped with a dedicated high speed InGaAs detector array working up to 1.7 μm and comes in three speed versions: 400, 800 and 1700 Hz. It allows you to visualize the ultra high speed features of your specific research application.

The TE1-cooling reduces dark current and improves signal to noise ratios for contrast-rich and stable imaging performance.

The camera head interfaces to your frame grabbing system via CameraLink (base, full or dual medium – depending on the version).

The Cheetah-640-CL is delivered with a software development kit which offers direct access to various camera settings and allows easy integration with your own high speed image grabbing system.

Benefits & features

  • Crisp motion analysis
    High frame rates and short exposures
  • World’s fastest InGaAs camera
    > 1700 fps at 640x512 resolution and 12 bit per pixel
  • Spectrograph compatible
    These cameras have mounting holes for spectrographs, making them suitable for (hyper)spectral imaging applications
  • Windowing to further increase frame rate
    A reduced window of interest will lead to a shorter frame read time and therefore high frame rates can be achieved
  • Reliable data transfer over dual CameraLink
    For high frame rate operation in 12 bit per pixel mode, the Cheetah-640-CL 1730Hz has to be connected via a dual CameraLink medium interface
  • Extending SWIR imaging to the visible
    VISNIR or visible enhanced InGaAs sensors for extended response from 500 to 1700 nm

Designed for use in

  • R&D (SWIR range)
    SWIR range is a relatively unexplored range and hence providing much research opportunities
  • Wavefront sensing
    A high-speed SWIR camera can be used in adaptive optics systems as a wavefront (or Shack-Hartmann) sensor. The camera is then used to measure a wavefront distortion. This technique is mainly used in free-space laser communication or astronomy
  • Hyperspectral imaging
    Combination of spectral imaging and 2D imaging. Our SWIR cameras are used for hyperspectral SWIR imaging
  • Situational awareness systems
    Able to detect heat signatures of intruders including human beings and vehicles. Especially useful at night
  • Oil electro-coalescence research for crude oil purification
    The behavior of small water drops falling through a viscous oil, can be investigated by using a SWIR camera. In the infrared spectrum from 900 to 1700 nm, any crude oil is nearly transparent.

Application notes
High speed SWIR imaging with the world's fastest SWIR camera The Cheetah-640CL is the fastest SWIR camera in the world.
Electroluminescense analysis using SWIR cameras speeds up the development of solar cells Electroluminescence analysis accelerates thin-film solar cell development
SWIR cameras for timely defect detection ensure higher yields in solar cell production. SWIR cameras for timely defect detection ensure higher yields.
SWIR cameras can see through crude oil The behaviour of small water drops falling through a viscous oil, can be investigated by using a SWIR camera. In the infrared spectrum from 900 to 1700 nm, any crude oil is nearly transparent. Why should one be interested in looking at water drops in oil?
