Dual pulse PIV laser
Vlite series lasers have been developed since 2000.This series are specifically designed for various 2D/3D PIV, Tomographic PIV and Time-resolved PIV application. With over 20 years of continuous improvement and upgrades, this product meets the demands of PIV applications in terms of beam uniformity, beam combining stability, and environmental adaptability.
Vlite series lasers provide both multimode and VRM mode beam profile with good beam quality. The long term engineering technologies have ensured the working reliability and stability of this series. Features as optical shutter, flow sensor, power supply interlock make sure the safety use as the top priority.
The Vlite series low repetition rate PIV dual-pulse lasers covers pulse energy ranging from 135mJ to 500mJ, with repetition rate 0-15Hz continuously adjustable, matching the frame rates of different PIV cameras. The design of beam uniformity and the thermally insensitive resonator make it an excellent illumination source for flow field lighting, with high adaptability to various environments.
The mechanical structure of the Vlite series focuses on the stability of beam combining, while the optical design emphasizes the consistency of dual-cavity lasers. The integrated design of the light arm and laser ensures user-friendly and efficient experiments. Additionally, the Vlite series offers a variety of optical light sheet, providing a wide range of optical solutions for flow field testing.
