Technology
Dynamic Image Analysis (DIA) Technology
The BeVision D3 Series employs advanced Dynamic Image Analysis (DIA) technology to deliver fast, accurate, and reproducible particle size and shape measurements.
During analysis, dispersed particles pass through a precisely defined detection zone. Uniform background illumination across the entire field of view creates high-contrast particle projections, which are captured in real time by a dual high-speed camera system. One camera focuses on coarse particles, while the other simultaneously captures fine particles, enabling complete size and shape distribution analysis across a wide measurement range in a single run.

Why DIA Method?
Dynamic Image Analysis (DIA) combines the strengths of traditional and modern particle characterization techniques while eliminating their limitations. By analyzing individual particles in motion, DIA delivers accurate, representative, and reproducible results for both particle size and shape—across a wide measurement range.

The dual-camera design allows simultaneous measurement of coarse and fine particles. This unique configuration provides comprehensive distribution information for wide-range samples with a single measurement, significantly improving efficiency and data integrity.
5-Megapixel CMOS Camera
Each camera is equipped with a global shutter, enabling sharp, blur-free imaging of fast-moving particles. High pixel resolution ensures precise contour detection and accurate size and shapeanalysis.
Green Parallel Planar Light Source
A uniform green planar light source ensures stable illumination across the entire field of view and consistent gray values in particle images. This simplifies image binarization and enhances measurement accuracy and repeatability.
Blue Light Source for Fine Particles
A dedicated blue light source delivers higherresolution imaging for fine particles, enhancing edge definition and ensuring clear capture of fine particle characteristics.
BV-F10 Free Fall Dispersion Unit
The BV-F10 Free Fall Dispersion Unit features patented dispersion technology designed for uniform and gentle dispersion of freeflowing powders and granules. By leveraging gravity-driven free fall, it ensures highly representative particle presentation without mechanical stress or particle damage.

Modular & Plug-and-Play Design
The BV-F10 features a modular, plug-and-play architecture with full software integration. All dispersion parameters are automatically controlled through the system software, enabling fast setup, consistent results, and excellent repeatability.
Samples are loaded into the funnel, where particles are metered and conveyed by a vibrating chute. The particles then pass through adjustable guide slots and fall freely through the detection zone under gravity. After measurement, all particles are collected in the recovery tray, ensuring complete sample recovery Features & Benefits
- Fully software-controlled adjustments
Funnel height, chute feeding rate and guide slot spacing are adjustable automatically via software. - Optimized particle dispersion
The beveled chute end redirects particles for uniform dispersion across the detection zone. - Controlled particle flow thickness
Adjustable guide slots control particle flow thickness, minimizing out-of-focus and particle overlap. - Intelligent feeding rate control

Applications
Typical Applications

Application Cases
Based on its wide measuring range, direct measurement principle, and broad compatibility with diverse sample types, the BeVision D3 Series can be widely used in many industries ranging from research to quality control, providing in-depth insights into particle analysis.
1. Excellent Repeatability
Example: Glass beads Glass bead particles are characterized in terms of length, diameter, and curvature. The measurement results closely align with intuitive visual assessments, confirming the accuracy and relevance of DIA-based morphology analysis. D10 D50 D90

The BeVision DIA Software provides 37+ particle size and shape parameters, enabling thorough characterization and objective evaluation of diverse particle morphologies.
Example: Petroleum catalyst Rod-like catalyst particles are characterized in terms of length, diameter, and curvature. The measurement results closely align with intuitive visual assessments, confirming the accuracy and relevance of DIA-based morphology analysis. 

3. Accurate Determination of Low-Content Oversize Particles
By leveraging advanced digital imaging technology and highspeed image capture, BeVision D3 Series achieves ultra-high detection efficiency. Even oversize particles present at extremely low concentrations can be accurately identified and quantified.
Example: Colorants Over 1 million colorant particles were analyzed within 6 minutes. The resulting size distribution revealed a small fraction of oversize particles, and captured images confirmed that each oversize particle was an agglomerate composed of multiple smaller colorant particles. 
4. Ultra-High Resolution for Narrow Distributions
The BeVision D3 Series analyzes every individual particle captured during measurement and performs statistical analysis across the full particle population, achieving single-particle resolution.
Example: Abrasives In abrasive materials, both oversize and undersize particles can negatively affect grinding performance. The BeVision D3 Series precisely quantifies the content of oversize and undersize particles, while also providing particle shape analysis to evaluate abrasive sharpness. 
5. Mixture Analysis
The BeVision DIA Software is a powerful data analysis platform that enables separation and analysis of mixed particle systems. Particle mixtures can be classified and filtered based on size, shape, or multiple parameters, allowing each fraction to be analyzed independently within a single dataset.
Example: Beans 
Direct measurement of mixed beans produces a bimodal particle size distribution (PSD). The smaller peak corresponds to mung beans, while the larger peak represents red beans. By applying size-based filtration, the software separates red beans and mung beans from the mixed dataset, enabling independent analysis of each component without additional measurements. 6. Fully Comparable with Sieving Results
The BeVision D3 Series uses a sieve-equivalent diameter aligned with the fundamental principles of sieving, delivering particle size distributions (PSD) that are highly consistent with traditional sieve analysis. Its dedicated sieve correlation function automatically compensates for systematic differences related to measurement principles, particle shape and statistical effects, and directly outputs sieving-correlated PSD results.
Example: Fertilizer PSDs measured by the BeVision D3 show excellent agreement with sieve analysis results. Users can switch seamlessly from mechanical sieving to the BeVision D3 system, significantly improving testing efficiency while reducing labor costs. 
7. Thickness Measurement of Flaky Particles
The BeVision D3 Series is capable of capturing crosssectional images of flaky particles during measurement, enabling automatic and direct thickness measurement.
Example: Soybean meal The thickness of the flaky soybean meal residue after pressing directly reflects the residual oil content. Conventional thickness measurement relies on manual caliper measurements of individual particles, resulting in extremely low efficiency and poor representativeness.
The BeVision D3 system automatically measures and outputs the thickness distribution and mean thickness, significantly improving measurement efficiency, repeatability, and statistical reliability
