A Polariscope helps detect internal stress and optical defects in transparent glass components by using polarized light. When glass contains residual stress, the material changes the way polarized light passes through it, creating visible patterns or color bands known as stress fringes.
During testing, the glass component is placed between polarized filters and examined under controlled lighting. Areas showing unusual patterns can indicate uneven stress distribution, which may result from improper cooling, heating, forming, or manufacturing processes.
Polariscope testing is useful for glass bottles, laboratory glassware, optical components, lenses, and other transparent products where dimensional accuracy and durability are important. It helps manufacturers identify stress-related weaknesses before products are used or shipped. By detecting these issues early, manufacturers can improve production processes, reduce breakage, and maintain consistent product quality. Presto Stantest Pvt Ltd offers reliable Polariscope testing solutions for evaluating stress in glass components.
