SV-1000, SV-2000, SV-3000 and RSV Series Strain Viewers

The SV-2000 Strain Viewer is a large-field polariscope (circular or plane polarization) suitable for inspection of nearly any size product. The standard viewing area is 400 x 500 mm (16 x 20 inch). The SV-2000 can be set up horizontally or vertically. The new SV-3000C Strain Viewer features circular polarization and an even larger field of view, 540 x 540 mm (21-1/4 x 21-1/4 inch).
In clear and translucent polymers, residual strains become visible when viewed with the SV-2000 and SV-3000 Strain Viewers. The strains appear as a colorful fringe pattern, which reveals a wealth of information. A comprehensive instruction manual teaches you how to interpret the color pattern. Quantitative measurements can also be obtained for many applications with an optional compensator, in accordance with ASTM test methods.

In production, this simple test can quickly identify defective parts and alert operators to adjust process parameters. The procedure is non-destructive and fast!

Unlike simple crossed polarizers, the SV-2000C and SV-3000C use circular polarizers which assure that stresses are properly observed regardless of specimen position or orientation. A plane-polarized model is available for glass applications – specify Model SV-2000P.

Typical applications of the SV-2000 and SV-3000 Strain Viewers include:

  • Thermoformed packaging
  • Medical components
  • Automotive components
