May 23, 2011 - Malvern releases a telephoto lens for particle size measurements. The lens for Insitec laser diffraction process systems enables the on-line measurement of larger particles, extending their application in the minerals, powder coatings and food industries, amongst others. By combining two different focal length lenses, the telephoto design concentrates an expanded measurement range, with a new upper limit of 2500 µm, into a physically shorter lens, just 160 mm in length. Compatible with all current Malvern Process products, the new lens can replace those 300 mm or 450 mm models currently in use in the field.
By increasing the upper sizing limit of Insitec technology from 1000 µm to 2500 µm, the 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. ISO13320 compliant and suitable for both wet and dry measurements, examples of applications for the new telephoto lens include: salt, continuous granulation, roller compaction, minerals pre-processing, atomised metal powder, fertilizer, agrochemicals and methyl cellulose, among others.
