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 companies manufacturing process.

Full Featured Software

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 Data Plots and Sample Information to .txt Format

Data plots can be saved for viewing in spreadsheets.

LamMaster 2 Standard Application

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 of the sample edges and the self-centering vise automatically aligns the sample and positions it for optimal performance. View the steps below showing a standard LamMaster 2 application.

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 away from the camera sensor, no matter the depth.

Laminar Stress of Tinted Glass

The LamMaster 2 works on tinted glass. The 6mm grey tinted glass, shown here, has 30% transmission through thickness.

LammMaster™ 2 Uses and Features

Uses of the LamMaster 2 Laminar Stress Measurement System include; manufacturing process set up, control of manufacturing processes, assessment of windshield glass quality, incoming material inspection, and installed glass assessments.

LamMaster™ 2 Features

  • Simple Turn-key System
  • Easy Specimen Loading
  • Minimal Specimen Preparation
  • Integrated Data Base
  • Calibration Standard
  • Thickness stress profile reporting:
    • Surface Compression
    • Center Tension Maximum
    • Location Zero Stress Points

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 to a correct measurement. It is also important to note that the stress plot and values are automatically updated as the settings are changed.
