HTabsOverviewThis optical spectrometer measures the size and shape of particles from 25 µm to 1550 µm (or optional 15 µm to 930 µm), liquid water content from 0.01 g/m3 to 3 g/m3 and airspeed to 200 m/sec. Key Features Optimized for the growth phase Get particle size distributions from 25 µm to 1550 µm, or 15 µm to 930 µm with optional 15-µm resolution. High-quality images Enable easy identification of particle types by generating high-quality images via 64 photodetectors. Use the optional grayscale option for enhanced images based on the density in different regions of the particle. Environmental data Record information on atmospheric temperature and pressure, aircraft velocity and altitude, and liquid water content (LWC) from 0.01 g/m3 to 3 g/m3.
