Polarizer Film

Ensure customer satisfaction by identifying all functional defects: ISRA solutions meet the highest standards for optical inspection systems, reliably detecting even low-contrast defects and micro-scratches in all relevant production stages.

The system aggregates data from separate inspection channels with varying optical concepts, before combining, classifying, storing and analyzing it. Hence, operators benefit from valuable direct insights into defect causes and locations, allowing them to initiate appropriate measures. The clearly structured data offers a sound basis for quality discussions with suppliers and customers.

The data is also used in multi-line production processes to compare the quality of finished products between individual lines and to take appropriate corrective measures to comply with the desired material quality.


100% Inline Surface Inspection of Polarizer Films

The system is designed for use in the various consecutive stages of polarizer film production. Operators are equipped with a powerful tool that allows them to minimize defect sources and reduce waste immediately. Only flawless material is delivered to customers.


Beyond Inspection Tools

ISRAs optional SMASH system add-ons deliver more than inspection: The Beyond Inspection Tools process the recorded inspection data and realize additional opportunities in optimization, validation, and data evaluation.

The following SMASH options achieve these potentials:

Full documentation of the entire surface area offers real-time information on material properties such as reflectivity and gloss. As a result, products like food or cosmetic packaging always meet the required quality specifications, eliminating costly customer complaints.

Verifying, optimizing and creating inspection recipes offline without having to shut down the production line reduces set-up times considerably, maximizing inspection efficiency and minimizing costs. The settings can be managed and standardized in a global and centralized manner, guaranteeing uniform quality specifications in every production line around the world.

Analysis of defect images and correct classification of all defects in predefined defect classes: Based on a wide variety of defect characteristics, this tool is an essential element in analyzing defects and their causes in the best possible way and preventing defects with minimal effort. The intuitive user interface helps operators to complete their tasks while ensuring that only flawless products are delivered to customers.

The software uses inspection data regarding the number and severity of defects, the quality of individual sections as well as the entire roll. It thereby classifies the roll condition according to various quality levels. This clearly indicates whether a roll meets the necessary specifications and can be delivered to the end customer.

The Rewind Manager enables users to control a rewinder with high precision, navigate accurately to surface defects such as insects or dirt spots, repair defects in a targeted way, and remove foreign particles. By turning waste into marketable products at low cost, you can improve your production yields and ensure customer satisfaction.

Calibration tools that can be integrated into the line quickly and easily, combined with dedicated software solutions. The ideal camera and lighting settings are checked and verified to ensure inspection results with increased repeatability.

Online validation tools for checking and documenting the correct function of the overall system: The software constantly monitors the accuracy of all geometric alignments and settings of the cameras, lighting, and parameters, even during the inspection process. 

Software for yield-boosting analysis of inspection data: The data can easily be prepared for statistical purposes, allowing you to create user-specific reports, e.g. in Excel.

Software solution designed to use inspection data to achieve maximum material yield: When calculating the ideal cut, the system also takes material distortion into account and automatically ejects only those areas identified as waste. It also ensures that the quality of the cut products can be easily matched to customer orders.

These two tools access both historic and current data and make it available for further analysis. They also allow users to monitor and modify inspection parameters. Multiple users can access the password-protected data simultaneously from various locations.
