Prism Film

Reduce customer complaints by ensuring delivery of prism films without any optical flaws: ISRA systems reliably master this complex optical inspection task. They reliably detect and classify structural defects, deeply embedded dirt particles or oil, and even minuscule defects in the 10-20 µm range.

Based on the inspection data, defect causes can be identified and eliminated immediately before the material reaches subsequent process steps.


100% Inline Surface Inspection of Prism Films

The system is designed for the automatic inspection of materials in both reflection and transmission. By providing real-time information about material properties and the extent to which specifications are met, it offers a quick and cost-effective alternative to elaborate and time-consuming laboratory tests.


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.
