Previous processes, in which only an intensity or colour comparison of the polarizing image took place, had to be extensively calibrated for each type of glass. The method developed by ilis, on the other hand, makes an objective and reproducible measurement of the stress birefringence which causes anisotropies. “The StrainScanner sees only the residual stress in the material. The measuring result is therefore not dependent on other influences such as coatings or tinting, for example. This means there is no need to constantly recalibrate the measuring system when changing products, which increases the reliability of the measuring results and, of course, saves time”, explains Henning Katte, Managing Director of ilis gmbh. Thanks to the inline process, the optical retardations recorded in thermally tempered glass are visualised immediately. Measuring process as the key to perfect tempering “Thanks to its measuring accuracy and reproducibility, the StrainScanner measuring results provide a never-seen-before depth of information with respect to heat treatment in thermal tempering”, says Schweitzer. The StrainScanner is thus the key to perfect tempering: “Using the measuring results, tempering systems can be precisely optimised. The slightest stress differences (optical retardations) are detected during production, which allows the plant operator to immediately correct the tempering parameters. With the StrainScanner, quality is no longer a matter of chance”, explains Hermann Dehner, Product Manager at arcon. Anisotropy is characterised by the isotropy value as a percentage. The isotropy value, which is calculated from the amount and orientation of stress birefringence using statistical methods, indicates the surface ratio of a pane which is free from disruptive stress birefringence effects (anisotropies), even under unfavourable conditions. In accordance with the current guidelines on visual quality, the isotropy value is determined for the entire pane and separately for the main zone and the edge zone. The quality of thermal tempering, the crucial stage of production, is transparent and can be documented. Measuring reports are available immediately and gapless.
