BeVision M1

The BeVision M1 provides an accurate analysis of particle size and shape in the range of 0.3 - 10,000 μm. Besides, the BeVision M1 can be a vital part of the surface cleanliness test and film defects inspection.

 

Through the precise auto-scanning and auto-focusing, the BeVision M1 capture high quality images, offering a full view without particle loss and distortion. 

 

The BeVision software helps you evaluate particle size and shape from 34 different aspects, and further organizes the data into an all - around validation of particles.

1. Why Image Analysis Method? 

 

• Easy
  Capture an image of particles, identify particles, then measure their size and shape. Every step of image analysis is easy and clear.

 

• Shape analysis
  Based on a direct view of particles, it is possible to analyze not only the size of particles, but also their shape. 

 

• Seeing is believing
  The image analysis method determines the size and shape of every individual particle and then sums it up to form a statistic. Details of particle size or shape distribution can be accurately provided.

 

2. Why Static Image Analysis Method?

 

• Clear vision
  In static image analyzers, precision microscopes and high-resolution cameras are specialized for high - quality particle images. 

 

• Undersized particle sensitivity
  The static image analysis method is sensitive to undersized particles; it is even possible to estimate the size of undersized particles.

 

• Small sample volume
  The static image analysis method requires a small volume of samples. A few drops of emulsions or a few micrograms of powders are enough to do a measurement.

 

3. Efficient Scanning Mode and Limit - breaking Panoramic Mode 

 

3.1 Scanning Mode 

The workflow of the BeVision M1 scanning mode is to capture an image first, then analyze the image while moving the stage, capture the next image once the stage has reached a new position, and repeat.

The BeVision software will display real-time results during the scanning process. The scanning mode is widely welcomed in different industries with its efficiency and reliability.

 

 

• Efficient and reliable scanning mode 
  Compared with the manual test, the automatic scanning process improves the test efficiency, doing the image capturing and stage moving simultaneously pushes the efficiency to the next level. The efficient scanning mode analyzes many particles in one test, thus strengthening the statistical significance of the result.

 

• Features and benefits

* Automatic scanning measures size and shape results fast and conveniently. 

* High-precision motion control guarantees less particle loss and no repeated capture.

 

 

3.2 Panoramic Mode 
The panoramic mode is to stitch separate images into a full view that records all particles in a millimeter-level region and keeps their shape details. 

With a panoramic image, it is easy to measure the total number of particles or defects, and to locate and classify them based on size and shape parameters.

 

• Features and benefits

* Automatic focus adjustment throughout scanning guarantees high-quality images and accurate results.

* Conditional filter based on size and characteristics helps particle count and classification. 

* Rescanning in a higher magnification helps in-depth analysis.

5. Typical Applications 

BeVision Software: Visualized Insights for You 

 

Automatic scan 

To ensure a reproducible result, the BeVision software can make a measurement automatically, following a saved standard operation procedure (SOP).

 

① Particle details

For irregularly shaped particles, it is hard to describe their size with a single dimension. Scanning over 180 different directions of each particle projection, the BeVision software is able to precisely analyze particles, and present the particle size and shape in 24 different parameters. The size and shape parameters are in compliance with ISO 9276 - 6.

 

② Distribution in total

Distribution curves and charts present particle size and shape distributions, and the scattering mode shows the relationship between two different particle size and shape parameters. All these charts, curves, and tables are customizable.

 

③ Locate particles

The BeVision software offers a single particle gallery that can be the direct way to locate particles with a specific appearance. Besides, the BeVision software allows users to find particles with specific characteristics, with a customizable filter.

 

④ Distribution in summary

The BeVision software offers statistics and typical values to describe particle size and shape distributions, e.g., the D[1,0], span value, and D90. The typical value chart is customizable.
