LAM MASTER 2
LamMaster 2
Laminar Stress Measurement System
The LamMaster™ 2 can solve cutability problems by assessing the annealing quality of float glass. The system provides a quantitative parabolic through-thickness stress profile that displays the top and bottom surface compression, as well as the center tension.
The easy-to-use software allows for quick and simple data collection for many different tints and thicknesses of float glass. The LamMaster 2 is a complete turnkey solution that will allow you to collect, analyze, export, and organize all the stress data you need to improve your company’s manufacturing process.
Full-Featured Software–LamMaster™
The LamMaster 2 Photoelastic Stress Analysis (PSA) System is managed with easy-to-use LamMaster™ software—a versatile tool for capturing, presenting, analyzing, and archiving photoelastic data.
LamMaster Software Features
Among many other features, the LamMaster Software provides:
One-Click Data Collection
Through-thickness Stress Profile Information
Automatic Color Balancing for Tinted Glass
Exporting of Data Plots and Sample Information to .txt Format
Data plots can be saved for viewing in spreadsheets.
Standard Applications of LamMaster 2
With the LamMaster 2, data collection is a snap. Simply insert the glass sample onto its spacer, dab a small amount of supplied matching index gel on the edges of the sample, and close the self-centering vise. The matching index gel minimizes the effects of imperfections, and the self-centering vise automatically aligns the sample and positions it for optimal performance. View the operational steps below, as well as LamMaster 2 applications.
2. Optical Gel
Optical gel allows for an unobstructed view through the LamMaster 2 windows and the glass sample.
3. Sample Placement
Set the glass sample onto the spacer. The height of the spacer ensures the glass sample is centered with the camera sensor.
4. Self-centering Jaws
The jaws of the LamMaster 2 are designed to place the sample at the ideal distance from the camera sensor, no matter the depth.
5. Data Collection
Place the light blocker over the sample and you’re ready to collect data.
Laminar Stress of Tinted Glass
The LamMaster 2 works on tinted glass. The 6mm grey tinted glass, shown here, has 30% transmission through-thickness.

Measurements
The LamMaster 2 provides stress outputs in terms of a parameters and a curve. The stresses at three locations—top surface, peak (center tension) and bottom surface of the specimen—are reported to the left of the plot. The locations of the zero stress points (Top Cross and Bottom Cross) are shown to the right of the plot. These values display the thicknesses of the top and bottom surface compression. The proper input of the specimen depth is important for a correct measurement. It is also important to note that the stress plot and values are automatically updated as the settings are changed.
