High-precision scanning technology for quality inspection of glass

The LineScanner is THE solution for all quality inspections of transparent flat glass products such as single sheets, insulating
glass, automotive glass, processed glass, polycarbonate or film. LineScanner inspects your products with extreme precision for all defects in quality and dimension. Its flexibility as well as its simple operation and installation allow it to be put into operation quickly and easily with minimum space requirements.

Especially in the glass industry, it's increasingly important, to meet the high demands of customers and partners. Since years Softsolution deals with the complex issue of checking the quality assessment of flat glass. Therefore we have developed a scanner which will revolutionize also your business!

Developed in Waidhofen/Ybbs, Softsolution produces unique LineScanners at the highest technical level. Many years of expertise and experience in the glass industry and with over 500 installations worldwide, Softsolution guarantees for excellent glass defect inspection systems on the market. Our LineScanner helps to deliver consistent quality to your customers and thus reduce the complaint ratios.


Artificial intelligence improves traditional automated methods, including error categorization in the LineScanner software.  Our system learns from errors and continuously improves the evaluation. False quality rejects are reduced.

In practice, operators on the line sometimes judge a software decision differently. The software adopts this change and takes it into account in future evaluations. The LineScanner learns from operator feedback and continuously adapts its categorization behavior. 

invest in the future

Manual glass quality assessment is a thing of the past!

The unique parallel light technology enables the LineScanner to be operated with the same setup to inspect single sheets
as well as finished insulation elements both horizontally and vertically. An automatic glass defect inspection system that excels with maximum flexibility and extreme ease of use.

The LineScanner inspects flat glass products for optical defects like scratches, inclusions, edge chips, screen printing, bars as well as dimensional defects with regard to overall dimensions, drill hole diameter and position. Glass thickness, the coating side and element structure can be quickly and easily examined. Thanks to the use of specially developed glass encoders, the position and size of defects can be optimally displayed.

Technological advantages

  • Resolutions of up to 400dpi and 16bit technology enabling a highly accurate scan image of the inspected object
  • An inspectation with 90° of all areas of the respective object , leads to stable , repeatable results
  • The proven , high-speed and high-resolution technology is based on scanning modules and an optimized parallel light illumination with LED 's.

linescanner - all-in-one system

glass inspections at the highest level

Surface quality 

The LineScanner tests your products with extreme precision for all quality and surface defects.

Dimension control

Thanks to the LineScanner, dimensional deficiencies can be checked and optical errors quickly detected and avoided.

Special quality checks

The inspection of the glass thickness, the coating side as well as the total deflection can be carried out easily and quickly by special quality checks. 

Tempering quality

With the use of the LineScanner on the tempering furnace, glass lites can be tested for anisotropy and edge stress in future. 

linescanner features


The newly developed LineScanner Management Console provides processors with an online overview of the current status of all scanners in production and thus integrates the scanners into the extensive automation and workflow control. This software tool records the quality and quantity of produced and scanned slices per line and gives a quick overview of all scanners in operation.

The LineScanner Management Console provides the user with the most important data (status of the line, service requirements - also foresighted - as well as current production figures with corresponding quality results) in real time. A complete documentation of the glass quality is indispensable and, thanks to lot and Industry 4.0, will be even easier in the future.
