Popis: Chemical tempering is increasing the areas of glass application in the wristwatch, glass and electronic industries. The optical waveguide effect in the surface layer of chemically tempered glass is a useful tool for measuring surface stress for quality and process control purposes. The theoretical basis, measuring techniques and apparatus are briefly reviewed.
