Introduce

Glass and plastics could have strain (internal stress) from the production process. The strain affect the quality considerably. Especially, strong tension cause the destruction and therefore the quality have to be closely controlled for safety. SVP series visualize the strain which is not watched by naked eye. And it helps quality control of glass and plastics.

Inspection method

1. Crossed Nicol
2. Parallel Nicol
3. Sensitive tint
4. Turn disk standard
5. Film array standard
6. Senarmont Compensation
7. Circularly polarization

Feature

• Allows you to observe and measure strain on transparent materials by means of observing fringe pattern and color while looking directly at the sample.
• White light source and sodium light source is switchable.
• Quantitative measurement of strain is possible by using the included film array standard.
