Comprehensive Particle Characterization Reliable Particle Detection System

Shimadzu’s iSpect DIA-10 Dynamic Image Analyzer combines particle size and image analysis technology The system utilizes a microcell and advanced optics to accurately and ef ciently detect particles. Using normal
to offer complete particle characterization. It can perform particle imaging, size analysis, and foreign lenses, the apparent size of particles can be affected by the depth of the particle relative to the lens. The iSpect
object detection, and obtain size distributions and number concentration, in as little as two minutes. DIA-10 uses a telecentric lens that maintains a constant image magni cation. This means that no matter where the
particle is located in the eld of vision, the system will accurately determine the size of the particle. The autofocus
function increases the imaging ef ciency which makes it possible to accurately detect foreign objects and obtain

Ef cient Image Acquisition

The microcell increases image acquisition ef ciency by passing particles through a narrow imaging area, which
optimizes the number of particles observed. Compared with a conventional cell and lens, the microcell clearly
