Edge Stress

Architectural Glass Edge Stress

We offer three options for measuring architectural glass edge stress. One is the GFP2600 that, when set at the edge of a test table or conveyor, can be configured as a very effective edge stress measurement tool. This versatile edge tool can move down the edge of the glass. Alternatively, the glass can be inspected as it moves through the edge stress measurement system. We also offer the EdgeMaster 2 as a viable edge stress measurement tool for flat glass. Since architectural glass is typically has no frit, the EdgeMaster 2 provides its own reflective surface behind the glass. Lastly, the GFP 1600, primarily utilized as an area stress measurement tool, can also use close-up lenses to determine edge stress; specifically the GFP1600 FPI (Flat Panel Illuminator) or a GFP1600 in conjunction with a Flex Illuminator.

Area Stress / Temper Patterns

Architectural Glass Area Stress / Temper Patterns

The GFP1600 FPI (Flat Panel Illuminator) is the most commonly used system for measuring area stress / temper patterns.

Another popular area stress / temper pattern measurement system is sold in cooperation with LiteSentry — the Osprey Complete™. The Osprey Complete is based on a line of GFP2600 real time stress measurement systems. A conveyor wide “strip” of stress is measured as the glass advances down the conveyor. The strip images are then “stitched” together using special software to form complete stress maps.

Thermal / Assembly Stress

Architectural Glass Thermal / Assembly Stress

The impact of thermal loads such as sun or deep freezing temperatures can determined with the GFP1600 using the REFLECT Illuminator. Even IGU’s can be tested if the inside surface of the glass is painted silver to reflect light. The individual pane of glass can be isolated, and the effects of sealant stiffness can be assessed.

Iridescence

Iridescence

Iridescence occurs when unbalanced residual temper stress selectively reflects naturally polarized light such as blue sky or water reflections. The GFP™1600 FPI is the instrument of choice for measuring iridescence. Stress Photonics’ GFP™ (Grey Field Polariscope) technology will measure the anisotropy and the directions of the incident planes that will excite maximum iridescence.
