Uniform light sheet
Control thickness, height, divergence, and edge quality.
Inspect, measure and process · Industry, inspection & flow
Particle image velocimetry
Turn a seeded flow field into a crisp, time-resolved velocity map.
Application focusUniform light sheet
Flow motion
Choose pulse duration and separation around velocity and scale.
Laser & camera
Make triggering and timing part of the source specification.
Why the source matters
PIV needs a uniform, stable light sheet with enough power or pulse energy for flow-field illumination and synchronized imaging.
The correct source is defined at the sample or process—not at the laser aperture. Wavelength and operating mode set the interaction; stability, delivery, timing, and control determine whether it stays useful in the complete system.

Application workflow
Design from the result backward.
Three decisions turn the application into a practical source specification.
Size the field
Define field of view, sheet thickness, working distance, seeding density, and camera sensitivity.
Choose CW or pulsed
Use velocity, frame rate, exposure, and temporal resolution to set operating mode.
Close the timing loop
Specify pulse separation, trigger levels, jitter, camera synchronization, and interlocks.
Selection guide
Match the architecture to the experiment.
These are starting architectures. Precisometer qualifies the final wavelength, output, delivery, control, and integration package against your setup.
- Wavelength band
- 532 nm CW and Q-switched platforms
- Operating mode
- CW illumination or synchronized pulsed illumination with sheet optics
Educational and slow flow
A CW laser with light-sheet optics supports continuous visualization.
Pulsed quantitative PIV
Select energy and pulse duration at the required repetition rate. For short image-pair separations, qualify a laser with the necessary pulse-pair capability and a compatible camera; the synchronizer alone cannot provide it.
Restricted geometry
Design beam steering, sheet optics, enclosure, and access around the test section.

PIV accessories
Choose sheet-forming optics, timing, beam delivery, remote operation and wavelength-specific eyewear with the laser. Confirm arm coatings and pulse-energy handling for the selected wavelength; choose goggles by the required protection rating and operating mode.
PIV Laser Light Sheet
Form a light sheet for planar particle image velocimetry and flow visualization. Adjustable working distance and a choice of fan angles let the optics be configured around the test section, incident beam and required sheet thickness.

Wind-tunnel aerodynamics
Illuminate a seeded plane to study wakes, boundary layers and flow around models. Specify field of view and velocity before choosing exposure and pulse timing.
Water-tunnel hydrodynamics
Map flow around submerged models, channels and propellers. Include window transmission, reflections and the sheet position in the optical layout.
Jets, sprays & mixing
Resolve particle displacement across a jet or mixing region. Match illumination energy, sheet thickness and image-pair separation to the measurement scale.
Microfluidic flow research
Qualify microscope illumination and detector sensitivity for small channels. Micro-PIV can use volume illumination rather than the sheet geometry used in larger test sections.
