New Technology in Drop-Size Measurement Instruments

Artium Technologies' (Sunnyvale, CA, www.artium.com) new diode-pumped phase Doppler interferometry systems use solid-state lasers incorporated into transmitting optics, eliminating losses that can result from fiber coupling, alignment, and degradation. According to Artium, the advantage of this approach to optical design is improved precision and a larger dynamic range, with higher resolution over the entire range.

The "PDI 100 MD" and "PDI 100 SC" systems measure drop size and one component of the velocity vector. Models in the 200 series simultaneously measure two components of the velocity vector, and models in the 300 series measure three components. The modular systems feature a separate receiver and transmitter for additional flexibility.
