OutlineOutline
Custom 128-photodiode array/front end with ~ 10 times the response speed of older probes (smaller 50 m pixels on the array).
10 m particles imaged at 170 m s-1 (front end up to 233 m s-1)Two independent imaging probes in one instrument provide stereo
images of some particles and measurement redundancy Large Sample Volume: 3 times the 2D-C Sample Volume
Example Showing how 2D-S Particle Inter-arrival Times are used to Remove Shattered
(and Splashed) Images
