Advanced Analysis of Internal Stresses in Flat Glass and Glass Containers
The digital polariscope is a versatile, high-performance measurement solution designed for the analysis of residual stresses in both tempered flat glass and glass containers, such as bottles and vials.
Thanks to direct computer connectivity and dedicated software, the instrument enables real-time visualization, data recording, and full traceability of measurement results, meeting the needs of production environments, quality control departments, and laboratories.
Dual Application, One Instrument
– Glass Containers – Bottles and Vials
The digital polariscope allows accurate analysis of internal stresses in glass containers, ensuring effective control of the structural quality of the product.
The instrument operates in compliance with ASTMC148-17, applying the polariscopic method for the evaluation of residual stresses generated during forming and cooling processes.
Visualization of interference fringes makes it possible to identify critical stress concentrations, contributing to the prevention of spontaneous breakage and improving container reliability.
– Tempered Flat Glass
In the flat glass sector, the digital polariscope represents an advanced solution for tempering quality control.
It enables detection and evaluation of internal stress distribution, supporting compliance with applicable standards and optimization of production processes.
