EasyInspect for window film inspection is an effective integrated inline inspection solution for window film production with the unique combination of inspection and VLT % monitoring for the complete with of the material.

Today's window film industry is characterized by versatile applications, high quality requirements and a growing material demand for both quantity and quality. Manufacturers who wish to provide customers reliably and timely with high-quality window films for architectural and automotive applications, can rely on EasyInspect. Together with EasyMeasure, quality control with Dr. Schenk's systems for window film inspection provides the leading edge advantage by not missing any defect or coating issue.

EasyInspect for window film inspection is used for local defect detection, e.g. for:  

  • Color dust detection
  • Scratch detection
  • Wrinkle detection
  • Bubble detection
  • Uncoated area detection
  • Bend detection
  • Dent detection

EasyMeasure for window film inspection monitors layer homogeneity. For a typical window film application of up to 2,000 mm width, more than 16,000 EasyMeasure brightness gauges guarantee consistent quality and detect critical deviations in the coating, sputtering, and evaporation processes. They monitor the optical density changes in the IR-absorbing and VLT-controlling layers with 16 bit gray level resolution (65,536 GL). 

EasyMeasure detects optical density variations revealing detailed information about the splitter and coating converting processes. This supports the production improvement as well as the quality grading of the final product.

EasyInspect & EasyMeasure for window film inspection use Dr. Schenk’s unique MIDA Technology to fully analyze all typical kinds of window film defects in one run. Thanks to ultra-high speed illumination multiplexing and multiple channel optics per one single camera line all of them can be detected and classified in substantially greater detail compared to any other inspection technology.
