The GASP® Polarimeter is also available with a video kit, and in a special CS version for use in measuring stress in TV glass.

Options & Accessories

Strainoptics' GASP® Polarimeter is a portable instrument for measuring surface stress in heat-strengthened and tempered glass. It can also be used to confirm stress-relief in annealed glass and to validate furnace settings for manufacturers of safety glass.

The standard GASP model is for flat or slightly curved surfaces, while the GASP-CS version is designed to accommodate a curvature greater than 8 inches (200 mm). Both models may be ordered with either a laser or fiberoptic light source. The laser model features a rechargeable battery pack and offers the broadest range of measurement, up to 25,000 psi (180 MPa).
