PIV Lasers
LaVision offers state-of-the-art dual cavity Nd:YAG lasers (532 nm) and Nd:YLF lasers (527 nm) for PIV applications.
For the different measurement tasks a wide range of output energies up to 400 mJ per pulse are available. Rates around 15 Hz are used for most liquid and air-based PIV applications. Repetition rates around 50, 100 and 200 Hz are best matched for time resolved measurements, for instance in water. For Laser Induced Fluorescence (LIF) and other related applications, 266 nm or 355 nm output options are available for most of the PIV lasers.
LaVision designs itself around compatibility, various optics for sheet and volume illumination as well as an articulated arm can easily be attached to the laser heads and offer easy and safe operation of the lasers.

Seeding Particles
For different flow applications proper seeding tracers are needed. Different solid & liquids particles are used depending on the application.
The tracers are characterised by sufficient light scattering, perfect signal quality and very good traceability to the flow. |
TYPES OF SEEDING
Seeding in Air HFSB soap fluid DEHS Fog fluid Seeding in Combustion Aerosil Titanium dioxide Graphite Seeding in Liquid Polyamide particles Glass hollow spheres Fluorescent particles |
Seeding Device
LaVision offers various models of seeding particle generators to be used for PIV and LDV applications. Each seeding device provides the appropriately-sized seeding particles to seed the flow field for velocity measurements. The different seeding devices can be used with different materials (liquid and solid).
