Visual inspection of stresses in glass and plastic.
The SV-1000/2000/3000 Strain Viewer is a polariscope suitable for inspection of residual strain.It can be set up horizontally or vertically.
In clear and translucent polymers, the strains appear as a colourful fringe patterns. Quantitative measurements can also be obtained for many applications with an optional compensator.
In production, this simple test can quickly identify defective parts and alert opera- tors to adjust process parameters..
The procedure is non-destructive and can be used on flat and curved samples.
With circular polarizers the stresses are properly observed regardless of specimen position or orientation.
Different sizes are available.
