SCALP-05 is a compact scattered light polariscope for depthwise stress measurement in sheet glass. SCALP-05 contains diode laser, optics and camera. Recording of the data and stress calculation is done by PC, connected over USB. Handling of the polariscope is simple – clean the glass, apply a drop of immersion liquid, place SCALP onto the same spot and click the start button in software. After 3 seconds the stress profile is shown on the screen of PC.
