Automatic transmission polariscope AP-07

Polariscope AP-07 is a computer controlled device designed for automatic stress measurement in solid and hollow axisymmetric glass products (drinking glasses, bottles, neck tubes of CRT bulbs, lamps, optical fibre preforms, etc.). It permits also edge stress measurement in glass plates and automotive glazing, thickness stress measurement in strips cut out from glass plates, and measurement of stress at edge corners. Photoelastic measurements are completely automatic and take from 2 to 10 seconds. After that stress distiribution in any section of the test object can be displayed on the screen. Diameter of the field of view is 40 mm. The measurement area can be easily displaced using the coordinate device with digital readout. Modern integrated photoelasticity algorithms are used for stress calculation from the measurement data. The polariscope can be used for stress measurement near the production line. Its handling does not need any knowledge about photoelasticity or stress analysis. The polariscope is delivered together with a laptop computer and software to control the measurements.

Scattered Light Polariscopes: SCALP-04 and SCALP-05

Scattered light polariscope SCALP-04 is meant for through-the-thickness stress measurement in architectural glass panels and automotive glazing. SCALP-05 is meant for stress measurement in automotive and solar glasses, chemically tempered glasses with smallest measurable thickness less than 1 mm. The polariscopes are computer controlled. Handling of the polariscope is extremely simple: just place the the device on the glass panel to be measured and press slightly the button on the left side of the device. After ten seconds the stress profile through the panel thickness is shown on the screen of the laptop. Some additional measurements are needed for stress measurement near the edges and holes.
