LED-Flashlight 300

White and blue light sources for volumetric flow field measurements

For volumetric flow field measurement techniques like Tomographic PIV and Shake-the-Box the usual laser illumination can often be replaced by high-power LED illumination. The LED-Flashlight 300 provides an array of +/-5° allows the illumination of measurement volumes with a cross section of about 300 x 100 mm² at 1 m working distance.

Optional Fresnel lenses can be used for smaller or larger cross sections.

Features
  • It is much compact, made up only by the LED module itself and a small power supply, allowing easy transportation and mounting, without potential laser misalignment. No maintenance efforts are needed
  • It is safe to operate, requiring no particular laser safety infrastructure and training
  • The incoherent light ensures high image quality with constant homogeneous particle brightness in time and space without laser speckle effects. Laser illumination often exhibits darker regions due to fringes in the laser beam profile causing less reliable particle tracking
  • The amount of light output is similar to high-repetition-rate lasers at a fraction of the cost
Key Applications
  • The LED-Flashlight 300 is designed for large measurement volumes in air, e.g. with Helium-filled soap bubbles (HFSB), or in water applications up to cubic meters. Especially for water applications LED-Flashlight 300 blue together with fluorescent particles and corresponding camera filters is highly recommended to suppress reflections and stray light from the environment
