Filter contamination Quick-Scan TM

Filter contamination analysis based on ISO 4406 / ISO 4407 / ISO-DIS 16232-10 / SS 2687

Macro system
System components: High resolution scanner + computer + DT-PA program



Micro system
System components :
Option1: High power upright or inverted microscope with polarized light(using stereomicroscope or zoom lens is not recommended for finding and measuring particles smaller than 100um)
+ Motorized control stage + computer + DT-PA program
We recommend using Marzhauser, Prior Scientific, Ludl, and ASI stage.

Option2: Stereomicroscope or Zoom lens with polarized light (recommended for finding larger size particles (over 100um) + Motorized control stage + computer + DT-PA program
Option3: Stereomicroscope or Zoom lens with polarized light (recommended for finding larger size particles (over 100um) + Mechanical XY stage + computer + iSolution DT which includes a feature that enables the user to scan the entire filter with mechanical stage while the system automatically capture and saves a composite image of the filter for analysis.

Filter contamination analysis based on
ISO 4406 / ISO 4407 / ISO-DIS 16232-10 / SS 2687

  • Extremely fast scanning: Scanning time while capturing image is quick and the result is precise.
  • Automatic image overlap compensation: Data is accumulated and adjusted live to compensate for image overlap.
  • Multiple scanning methods: Circular, rectangle, and square shape based on application needs.
  • Theta compensation for camera and stage mis-alignment: Images are automatically compensated for camera and / or stage mis - alignment.
  • Automatic shading correction: During scanning, shading correction is applied automatically.
  • Automatic focus adjustment: During scanning, Z focus is adjusted automatically as the stage moves into the X and Y direction.
  • Stage position memory: X / Y / Z stage positions are memorized for future recall.
  • One click position recall: A single mouse click on the mosaic image brings the stage to the exact location for further observation, allowing the user to switch to a higher magnification objective lens more detailed inspection and image capture.
  • Export to Excel template: Result can also be exported to customized Excel reports.
  • Seeing results quickly: The largest particles are highlighted for better observation.
  • Automatic detection Reflective(metal), Particles, and Fibers: Using reference image, Reflective(metal), Particles, and Fibers are defined and classified automatically.







Report based on industry standards


Detection and classification of Particle, Metal, and Fiber




Largest particles or metals are highlighted


Customized classification by request


Automatic Detection of Metal Particles (Two different methods can be used selectively)
  • Simple thresholding methods in ordinary image analysis routines are not enough to define organic and inorganic objects such as metallic and non-metallic objects. We incorporate special algorithms for finding visual textural differences and other parameters in defining and classifying metallic and non-metallic objects having similar color and brightness.

Customized Particle Analysis
  • Analysis can be applied to a compposite image or within a selected field of interest (FOI). Annotations such as text and scale bars can be added to the image for more detail.




Particle Shape and Size Analysis
  • Particles over several images are characterized on the basis of shape and size. Customized parameters for selecting and sorting the data are available, producing volume distribution and other statistics. The Particle Gallery shows each object's shape in each classification range in the data collector table. All resulting data as well as the Particle Gallery can be exported to MS Excel by a simple mouse click.
