ISRA VISION Introduces Advanced Inline Inspection for Polarisation Films

ISRA VISION has further enhanced its optical inline inspection system for polarisation films. It has equipped it with a new sensor system that enables even better detection of typical defects such as scratches, Harley Bear, and perforations. Thanks to a special additional lens, the polarisation angle of the camera can be automatically changed. Pre-configured product-specific profiles can be transmitted online to the camera. There is no need to halt production to adjust. This not only helps to further optimise the inspection performance and the quality of the end product but also saves time and costs.
With SMASH, ISRA VISION offers an automatic surface inspection solution for the production of optical films such as prism films, polariser films, protective films, and window films. Thanks to high-resolution line-scan cameras and state-of-the-art lighting technology, the system can recognise even the tiniest defects such as Harley bear, scratches, pinholes, haze, coating faults, polarising defects, oil spots, structural defects and inhomogeneities in real-time, even at line speeds of up to 150 m/min.
The trainable defect classifier QuickTeach helps to simplify and speed up system start-up. A comprehensive set of tools for data recording, analysis, and reporting functions rounds off the package.
The polarising filter ISRA VISION uses for the inline inspection of polariser films allows automatic adjustment of the polarising angle in the event of phase changes in the film. It sets the polariser to full-light extinction or other predefined settings without the need to stop production. Because the camera thus always receives an optimum input signal, defects can be recognised even more efficiently and reliably. This helps to optimise product output and product quality further.
Product-specific settings can be pre-configured as recipes and transmitted online to the camera during operation. Compared with the manual setting of the polarisation angle, the automatic adjustment ensures higher precision and also saves both time and money.
By using this new polarising filter, the waste generated during production start-up can typically be reduced by up to 1,000 m2 per 8-hour shift, depending on the roll width and line speed. This not only increases the amount of saleable products but also protects resources by reducing material consumption and production waste.
