Cameras for Scalar Imaging

For scalar laser imaging in gas flows in most cases intensified cameras are used. Image intensifiers amplify weak light signals up to single photon sensitivity, can detect UV-light and offer fast gating for short exposure times down to 3 ns. Different types of intensifiers and intensified cameras are offered:

  • lens-coupled intensifiers (IROs)
  • lens-coupled intensified cameras
  • fiber-coupled intensified cameras

LaVision’s IRO lens-coupled image intensifiers allow easy upgrade of all kind of cameras for intensified imaging performance when needed. LaVision’s DaVis software controls the intensifier settings for gate, gain and delay via our universal IRO controller.

System Features of
IRO Image Intensifiers
  • lens-coupling between camera and IRO for optimized image quality
  • intensifier can be easily removed from camera when not needed
  • 5 ns minimum exposure time
  • maximum light detection sensitivity
  • IRO operation (gate, gain, delay) under DaVis software control
