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 CAV is designed for a customized, fully-automated inspection of particles and cosmetic defects of vials with liquid or lyophilized products.

WILCO new machine for visual inspection

Static optical path OptiX

Maximum inspection process reliability due to reduction of vibrations within the inspection system. No operator adjustments during format change on cameras or light are required and therewith prevents miss alignments.

Customized inspection setup

The selection of inspection algorithms is project specific and therefore reaching maximum detection rates. The inspection platform provides scalable processing units and allows simple upgrade to new inspection tasks.

Machine design acc. GMP

The inspection platform is designed for simple cleaning and a fast overall changeover between formats. Additionally critical components such as cameras are protected from dust and environmental conditions.

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.
