EasyInspect uses Dr. Schenk’s unique MIDA Technology so one defect generates multiple images to deliver the most comprehensive material analysis on the market. Dr. Schenk inspection and measurement solutions are available for nearly every step in the production of materials with structured surfaces.

Advanced image processing based on ultra high sensitive cameras and sophisticated illumination.

1. Ultra-fast TDI cameras with CMOS technology

Dr. Schenk TDI cameras offer the unique combination of high resolution defect images with superior down and cross web resolution – particularly at high production speeds.

Your benefits from Dr. Schenk TDI cameras are:

• Optimum defect detection
• Highly improved sensitivity (especially for low-contrast defect detection)
• Facilitation of high-speed production

Highly precise measurement of optical, and mechanical properties, such as geometry, surface flatness, deformation, or layer thickness.

2. MIDA – Multiple Image Defect Analysis

Dr. Schenk’s MIDA allows combining different viewing angles in a single camera row. Using MIDA, you can move from the conventional

…one view per camera row solution

…to multiple views per camera row.

MIDA: see defects from all perspectives

and Dr. Schenk’s dedicated gels optics (B).

Right: same metal void in metallized packaging film using regular illumination (C)

and Dr. Schenk’s dedicated voids optics (D).

Your benefits from MIDA are:

• Savings in required line space
• Reduced investment
• Improved detection & classification

3. MIDA X: best defect detection and classification through visual intelligence

MIDA X is the next generation of defect detection and classification. It uses highly scalable software running on proprietary Dr. Schenk multi-core CPUs/GPUs to push the limits of defect analysis: neighboring defect areas are also examined to retrieve further information, for example a defect’s true form.

The MIDA X advanced image processing tools and full contextual defect analysis work just like the human eye and brain – only better. MIDA X is faster and offers consistent results 24/7.

Your benefits from MIDA X are:

• Differentiating defects from background noise in highly structured or irregular materials
• Preventing detection of pseudo-defects
• Clearly identifying defect areas and no-care areas
• Merging long, fragmented defects, such as fibers, into one

4. EasyMeasure – look beyond local defect detection

Expand Dr. Schenk’s EasyInspect for local defect detection with EasyMeasure for complete material monitoring to optimize your quality control as well as your production process. EasyMeasure continuously monitors optical material properties, including homogeneity of coating, opacity, breathability, HAZE, optical density and many more. Optical density for example can be represented as a numerical value for increased quality assurance.

Your benefits from EasyMeasure are:

• Monitoring of optical material properties for the complete width of the material
• No additional hardware required, thus keeping investment low
• Savings on expensive finishing processes & time
