Product Introduction

KASON-PSM1 polariscope stress meter is mainly used in glass bottle factories, optical instrument factories, glass factories and laboratories to measure the stress values of optical glass, glass products, vials, ampoules, liquor bottles, beer bottles and other optical materials.

Product Features

The glass stress tester is an instrument that inspects internal stress in glass or crystal birefringence based on the principle of polarized light interference. Equipped with a sensitive tint plate and adopting the 1/4 wave plate compensation method, the instrument can not only qualitatively or semi-quantitatively measure the internal stress of glass according to the interference color order in the polarization field, but also accurately measure the internal stress value of glass.
