Cavitar Cavilux HF light sheet optic adaptor is a valuable tool in the high speed camera world.  Laser light can be formed in a thin sheet of light that can be used to take a 2D slice through a 3D flow.

 

Illumination laser light sheets are used with high speed cameras in the following applications:

  • Flow Visualisation
  • PIV ( Particle Image Velocimetry) 
  • Spray Patternation
  • Fluorescence Microscopy
  • Combustion Analysis

Measured images of laser lines at five different working distances (WD)
  • Line thickness (FWHM): -0.1 to 0.5mm for working distances from 100 to 500 mm
  • Line width (FWHM): -75 to 190 mm with working distance from 120 to 500 mm
  • Working distance: adjustable from approx. 100 to 5000mm
  • Weight: approximately 100 grams
  • Fiber length: 0.5 - 1m

Measured line thickness profiles at different working distances. Light was focused at each working distance. Light sheet aperture was 7 mm.

Measured line thickness FWHM-values and estimate for longer working distance. Light sheet aperture 7 mm.

Measured line width profiles at working distances 100, 150 (dotted), 200, 400, 500 and 600 mm.
