Model# SCALP

Scattered Light Polariscope

A portable instrument for fast measuring glass stress in field.

SCALP uses the scattered light method to determine through the thickness stress distribution (residual and loading stress) in annealed, heat-strengthened and fully tempered flat glass products. All functional components of SCALP (polarized diode laser, optical modulator, CMOS camera and all related optics) are built into a robust aluminium case. Connecting with computer can realize field measurement.
