GFP1600 FPI
Large Area Stress Measurement System
The GFP™1600 FPI (Flat Panel Illuminator) is a large area stress imaging system. Any number of LED light panels can be combined to accommodate any size glass product including full automotive windshields, sidelites, backlites, and sunroofs, or any size architectural glass.
The GFP1600 FPI’s high sensitivity (1 nm) and high retardation range (1000 nm) result in beautifully detailed digital stress images.
Full-Featured Software–DeltaVision™
The GFP1600 FPI Photoelastic Stress Analysis (PSA) System is managed with easy-to-use DeltaVision™ software—a versatile tool for capturing, presenting, analyzing, and archiving photoelastic data.
DeltaVision™ Features
Among many other features, the DeltaVision provides:
- Complete control of RGB LED illuminator
- Calibration in retardation: MPa or psi
- Detailed analysis with point, line, and area interrogation
- Edge compression and tension values via the Edge-Stress Tool
- Data export to Excel or similar
GFP1600 FPI Applications
The GFP1600, in conjunction with the FPI (Flat Panel Illuminator), allows for full-field stress images of large glass samples. Easily collect accurate and quantifiable stress data over an entire windshield, window, or other large piece of glass to solve problems in manufacturing, or to create a database of residual stress information.

GFP1600 FPI Features
The GFP1600 FPI allows for full-field stress images of large glass samples. Easily collect accurate and quantifiable stress data over an entire windshield, window, or other large piece of glass to solve problems in manufacturing, or to create a baseline of images for future reference.
With the GFP1600 FPI, users can easily document stresses created in the forming process due to:
- Thermal gradients
- Air currents
- Crease lines
- Defrosters
- Buss bars
- Solder tabs
- Temper patterns
Measurement and Data Analysis Tools
From automotive glass to architectural glass design and manufacturing, the GFP™1600 FPI (Flat Panel Illuminator) is a versatile, capable solution for all of your stress analysis needs. The system has numerous software tools along with a variety of lenses and accessories for imaging and data analysis. View large area stress images, or zoom in for a closeup. Highlight any area and zoom in with a close-up lens to create detailed stress images. (FOV 50mm x 60mm).
Clear Visualization
The GFP1600 System acquires stress data by collecting images via a rotating optics wheel. Various polarizer orientations, as well as wave plates, allow the system to calculate stress levels up to +/- 1000nm in seconds.
The images on the right show the various stress states, including Shear 0, Shear 45, and Shear Max. The GFP1600 FPI can also output a visible light image for a direct comparison to the sample being measured.
