With Screenscan-RD (Reflected Distortion) offered by Isra Vision, it is now possible for the first time ever to objectively assess the reflection quality of curved automotive glass. As such, the innovative system makes it possible to leave behind manual inspection processes, which in view of the ever growing complexity of the various glass forms can no longer efficiently satisfy the demands of today’s industry. With its leading-edge functions, based on patented no-contact measuring processes, Screenscan-RD guarantees the production of highly attractive automotive windshields with absolutely no flaws, thus achieves maximum attractiveness, safety, and the potential for enormous savings.

Processes specifically developed by ISRA and based on stereo deflectometry can be used to evaluate the reflective optics of windshields, rear windows and side window panes. The system allows for a measuring accuracy into the milli-dioptric range. Instead of the surface height, it calculates the glass curvature precisely , irrespective of the angle of vision – and this within the most common cycle times. This data can be used to satisfy the ever increasing demands that are required of a multi-functional windshield: Camera-assist ranges and head-up display can only be applied properly with a consistent and reliable level of quality. Moreover, in order for a windshield wiper to work efficiently, a flawless curvature is necessary; this can only be achieved with continuous inspection and process optimisation.

Inspection data is key to process optimisation ISRA equips Screenscan-RD with intelligent tools, which offer much more than just inspection. It starts with a target-actual comparative feature against CAD data, and is followed by an evaluation option to compare freely definable critical values and individually particularly relevant regions. Even a simulation using known grid processes is defined in the software. Tools for data analysis round off the full range of additional functions: The system continuously records quality data, which is visualized and compiled in log files. Manufacturers are given a wealth of valuable information which they can use for process optimisation and the opportunity to reliably prove the quality of their products to end customers. Leading automotive glass manufacturers around the world place their trust in this revolutionary principle.

Screenscan-RD is the unique solution that offers an objective and quantifiable assessment of the aesthetic characteristics of automotive glass. Its contact-free optical 3D inline measuring process guarantees glass manufacturers a high level of productivity and a verified, consistently high quality. This equates to significant production cost savings. With Screenscan-RD, the risk of delivering automotive windows with any aesthetically disturbing distortions that would adversely impact the multi-functional capabilities of the windshield is almost entirely eliminated.
