Slice Analysis

DIAS-1600 Digital Stress Analyzer

Evaluating a glass slice in cross-section to verify surface compression and mid-plane tension is a highly recommended QC practice.

Strainoptics offers two polarimeter systems designed for this application, the PS-100-MW Polarimeter and the DIAS-1600 Digital Image Analysis System.

PS-100-MW Polarimeter. Supplied with a 75mm high-intensity light source, a microscope and a measuring wedge assembly.

The DIAS-1600 Digital Stress Analyzer is a machine-vision, PC-based workstation for off-line stress inspection. Measurement results are reported for individual points, as graphs of stress vs. position along any line, or as full-field color-coded quantitative stress maps.

Use of the DIAS-1600 provides the following benefits:

• Quantitative retardation/birefringence or stress measurements in a user-friendly, menu-driven PC format
• Easy visual inspection, eliminating errors and decisions based on the user's visual judgement
• Reproducible, accurate results
• Automatic calibration

Refractive Index Matching Fluid:

• Available in 4 oz (120 cc), 16 oz (473 cc), or 1 gal (3785 cc) sizes
• RI = 1.52 for use with float glass in immersion cells only - (For GASP use, specify RI = 1.54)
