The department of Visual Inspection Systems (SPR) develops and delivers systems for Automatic Visual Inspection tasks in industry. SPR belongs to the Inspection and Visual Testing division and to the core competencies Optronics.

The main areas of application are currently automatic inspection of blister packs in the pharmaceutical industry, automatic sorting of bulk goods, inspection of surfaces, color measurement of granulate and print-layout checking.
All of these applications are characterized by the fact that the inspection is performed at high throughput rates in real time during the manufacturing process. This calls for high performance image evaluation systems.
The imaging sensors used are high-resolution line-scan cameras of various types (color and grey scale). The image acquisition equipment is all customized for the specific task at hand, making particular use of folded beam paths and LED flash illumination.

The products made by this department are in industrial use worldwide. Marketing and servicing are primarily provided by partner companies, but the division also develops some products specifically for end users, in which case it is also responsible for installation and servicing.
