• Two 128-photodiode linear arrays work independently as high-speed and high-resolution optical imaging probes.
• Captures two-dimensional images of particles passing through sample volume where laser beams overlap.
• The region where the beams overlap uniquely defines the depth-of-field (and thus the sample volume) for small particles.
• Response time is 10 times faster than the 2D-C.
• Particles as small as 10 microns imaged at 200 m/s.
• Greatly improved determination of sample volume and sizing of small particles less than 100 microns.
• Data rates up to 13 MB per second, compressed into binary file.
• Fits in standard PMS 2D canister and uses standard wiring.
