Large Field Polariscopes – Strainoptics Large Strain Viewers for Qualitative Inspection of Glass Stress Patterns
Strainoptics’ PS-100-C148 is the Polarimeter System you need to measure glass containers in accordance with ASTM C148 - Standard Test Methods for Polariscopic Examination of Glass Containers and C1426. The instrument is also sold with our RPLP-100 Full Wave Tint Plate. The Strainoptics PS-100-C148 Polarimeter System has a 200 x 200 mm viewing area and analyzer, which is calibrated in degrees for temper number. If you are measuring your glass containers in accordance with ASTM C148, this Strainoptics system is a must.
Contact us if you are uncertain if the PS-100-C148 is the best choice for your application.
Accessories such as tint plates, babinet or babinet soleil compensators, strain disc sets, microscopes, immersion cells, camera adapters, or other options can be used with most systems to suit the application.
Strain Viewers (polariscopes) are suitable for inspection of nearly any size product. In clear and translucent polymers, residual strains become visible when viewed with Strainoptics’ polariscopes. 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. In production, this simple test can quickly identify defective parts and alert operators to adjust process parameters. The procedure is non-destructive and fast!
Quantitative measurements can also be obtained for many applications with an optional compensator, in accordance with ASTM test methods.
The SV-3000 polariscope is similar to the SV-2000 but is bigger, with a viewing area of 22 inches (560 mm) square. This polariscope is large and industrial and can handle multiple items at a time.
Separate vertically oriented analyzer and polarized illuminator for larger or deeper samples. Horizontal lightpath only.
Viewing area: 250 x 280 mm (10 x 11 inches).
Large-field, vertical lightpath. Adjustable height analyzer for larger or taller samples. Viewing area: 250 x 280 mm (10 x 11 inches).
Unlike simple crossed polarizers, our polariscopes 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-2000-P.
Typical applications of Strainoptics’ polariscopes (strain viewers) include:
-
Thermoformed packaging
-
Medical components
-
Automotive components
