Glass Seals

Strainoptics offers two polarimeter systems designed for measuring stress at glass seals, 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

The DIAS-1600 produces FAST inspection results!
