By increasing the upper sizing limit of Insitec technology from 1000 [micro] to 2500 [micro], Malvern's new telephoto lens
broadens access to reliable continuous laser diffraction particle size measurement, enabling customers to tackle new applications and increase the efficiency of current systems-Additional benefits include improved stability and ease of alignment, better vibration tolerance, robustness to temperature, and reduced space requirement without compromising measurement quality at lower size limits.
