Product Details

The confocal microPIV system is used when narrow depth of field is required, with the goal of slicing through the microchannel to get a representative vector field in each slice. The confocal optics involve a laser-illuminated rotating disc to focus the laser beam at a very tiny spot, reducing the depth of field to a few microns. Generally, confocal optics are an add-on component to a standard microscope. There is also a time-resolved confocal system in which the confocal optics and high speed camera are used together to capture the velocity field with both high temporal resolution and small depth of field.

FEATURES AND BENEFITS

  • Slices of measurements with micron-range depth of field to obtain flow profiles in microchannel flow using confocal scanning capability
  • Patented techniques for image capture and analysis provide unmatched microflow measurement capabilities
  • Fully functional inverted microscope approach is designed to allow measurement of microflow as well as other measurement requirements
  • Ensemble correlation analysis method offers extremely high spatial resolution to get boundary layer velocity profile at the near wall of the channel
  • Adaptable with both high-speed and low-speed cameras
  • Illumination of the measurement region provided by a high-power CW laser
  • Insight 4G Software offers complete system control, data collection, display, and analysis

APPLICATIONS

  • Accurate flow profile measurements using the confocal, scanning-based microPIV system
  • Also appropriate for measurements of flow in microchannels using the standard microPIV arrangement
  • Flow measurements in MEMS, microchannels, and drug delivery
