System Information

General Description: Micro-Particle Image Velocimetry (PIV) system is designed to measure velocity fields of particle seeded flows with micron scale spatial resolution using PIV techniques. The light source is typically a double pulsed Nd:YAG laser that is coupled through an optical fiber into a fluorescence microscope and focused with a high numerical aperture on a microfluidic device.

The microflow is seeded with fluorescent particles. A microscope lens collects the particle signal that has a longer wavelength than the illuminating light. This signal is separated from the laser light by a filter cube and is recorded by a double-frame CCD camera. The double frame images are evaluated with conventional PIV algorithms.

Capabilities:

  • Nano S 30-30 PIV Pulsed Nd:YAG Lasers are ultra-compact and rugged offering repetition rates to 30Hz and energies up to 30mJ at 532nm.
  • Repetition rate: 0 – 30 Hertz.
  • Dedicated laser head and controls for PIV.
  • Carl Zeiss Observer Z1m inverted research-grade material microscope with motorized stand, focus control, and 3 x optovar turrets.
  • Equipped for all relevant contrasting methods.
  • 6-place reflector turret for convenient change of reflector modules, with 10x, 20x, 40x, and 63x objectives.
  • Automated components of the reflected light beam path providing the highest level of reproducibility.
  • Contrast and light managers for automatically controlled microscope settings.
  • New LED illuminating concept, no alignment and no lamp change required.
  • Accurate measurements in microchannels, microfluidics, MEMS applications, and drug delivery.
  • Scientific CMOS Imager with a 5.5 megapixel (2560h x 2160v) resolution and a frame rate of 100 frames/second.
