Automated Visual Inspection

Parenteral drug products are required to be 100% visually inspected. As each product and its packaging define their specific inspection task, standardized inspection setups may lead to a high level of false rejects and underperforming visual inspection. A highly customized solution, in contrast, provides the opportunity to significantly improve detection rates and to reduce false reject rates.


The automated visual inspection platform VISION CV is designed for a customized, fully-automated inspection of particles and cosmetic defects of vials with liquid or lyophilized products.

Static optical path

The Vision CV platform does not use any swiveling mirrors or moving cameras. Therfore, the risk of synchronization failures or vibration in the inspection path is prevented.

Customized inspection setup

The platform has the capacity to integrate up to 13 inspection stations, which allows custom-design vision setups for the best inspection results.

Latest Image processing algorythms

Our large toolbox of image processing algorithms allows us to configure specific inspection algorithms combinations to achieve the best inspection results for each defect category.

The vision machine combines solid and proven mechanical engineering according to GMP standards with the latest digital inspection technology.

Container transportation system

The vial transportation system was designed to gently transport the test samples through the inspection stations with the goal of reducing bubble creation and vibrations that might impact the inspection result.

Cosmetic and particle inspection

The cosmetic inspection stations provide container rotation of 360° checking for cracks, scratches and other defects on the container and closure.

Particulates are inspected using image subtraction and corresponding algorithms.

Customized configuration of camera stations

High-resolution image sequences are recorded by several camera stations. Spinning profiles may be adjusted for different particle characteristics such as floating, or heavy particles. Additional camera stations allow for inspection of geometric measurements and detection of discoloration.
