Particle Measurement Lasers

What are Particle Measurement Lasers?

Particle measurement is widely deployed as a means for counting and sizing the number of particles in both air and fluids. Three primary particle measurement methodologies are employed currently optical particle counting, dynamic light scattering, and particle image velocimetry. While dynamic light scattering and optical particle counting look at two different aspects of the scattered light, temporal fluctuations and intensity fluctuations respectively, they both require similar laser specifications. These lasers must then have a high-quality continuous-wave TEM00 laser. Otherwise, the speckle pattern of the multi-mode beam will interfere with the measurement of the scattered light. Particle image velocimetry, on the other hand, is based on synchronizing a pulsed laser and time-gated camera which are trigged at the same time so that each image can be precisely mapped to a point in time. For all of these applications, the actual wavelength of the laser is not highly critical, but it is generally preferred that visible lasers are used to maximize the sensitivity of the detectors. On this page, you will find a list of all of the particle measurement lasers we offer, including both diode and diode-pumped solid-state lasers.
