The history of Microtrac Inc. includes not only an array of technologically advanced products, but also many significant developments in the field of light scattering as well. The time line below traces the legacy of our technology, our product portfolio, and our company – the originator that introduced laser particle size measurement instruments to the world.

Microtrac instrumentation has come a long way from its humble beginnings embodied in the original Microtrac model 7991. The story began with the development of the laser by Bell Labs in 1959, plus its advancements during ensuing years, and the advent of the first commercially available microprocessor chip (Intel 4004). Below are the salient developments of the continuing Microtrac story that includes more than 20 patents covering light scattering technology.
