BeVision M1 - Automated Static Image Analyzer

Bettersize Instruments’ BeVision M1 automated static image analyzer is an automated image scanning system suited to applications involving cleanliness analysis of particulates found on filters.

The BeVision M1 is equipped with a programmable motorized stage, metallurgical microscope, auto-focus function, and high-resolution CMOS. These features allow the instrument to capture and recognize each particle in a sample, automatically stitching the individual images to create a larger overview image.

The BeVision M1 is an integral part of surface cleanliness measurements. Its many features and benefits include:

A wide measurement range of 1 µm to 10,000 µm

A high-speed CCD camera

Results compliant with ISO 9276-6

Twenty-four different particle shape and size parameters

Highly reproducible results

Powerful software eases workload

An automatic sample stage that offers high position accuracy

Advantages of Using the Image Analysis Method

Every step of image analysis is easy to understand; from directly capturing an image of particles and identifying them, to measuring their shape and size.

This data can be summed up in statistical form to provide an accurate and detailed distribution of particle shape or size.

Using static image analysis offers even more specific benefits. High-quality particle images can be obtained via static image analyzers due to their use of specialized precision microscopes and high-resolution cameras.

The sensitivity of this method means it is possible to measure undersized particles.

Only a small sample volume is required to obtain a measurement; for example, a few micrograms of powders or a few drops of emulsions.

The BeVision M1 can be used in scanning or panoramic mode.

Using the BeVision M1 in Scanning or Panoramic Mode

Scanning Mode

The BeVision M1’s scanning mode works by first capturing an image and then analyzing it while moving to the next stage. After capturing the next image (once the stage has reached a new position), this next image is analyzed, and the process is repeated.

The BeVision software can also display real-time results during the scanning process. The instrument’s scanning mode is widely used in a range of industries due to its efficiency and reliability.

When compared to manual testing, this automatic scanning process offers greater efficiency as it performs the image capturing and stage moving processes simultaneously. This scanning mode can also analyze a large number of particles in one test, giving added weight to the statistical significance of the results.

Panoramic Mode

The BeVision M1’s panoramic mode involves stitching a series of separate images into a single panorama before carrying out any analysis.

A panorama facilitates the easy measurement of the total number of particles in the region as well as the size and shape of every particle. This is the case even when the particle is oversized. The automotive and pharmaceutical industries are two sectors where an accurate particle number is of vital importance.

Panoramas obtained by utilizing the BeVision M1 will record all particles dispersed in a region at the millimeter level and will retain their shape details. Clear panoramas assist in the accurate counting of particles in the macro-region. They also allow for the analysis of the shape and size of particles without any leftovers.
