DRK506 Polarization Stress Meter

DRK506 polarized light stress meter is suitable for pharmaceutical companies, glass products factories, laboratories and other enterprises to measure the stress value of optical glass, glass products and other optical materials.

Test Principle
An instrument used to examine the internal stress of glass or the birefringence effect of crystals by applying the principle of polarized light interference. Because the instrument is equipped with a sensitive color plate and uses a quarter wave plate compensation method, the instrument can not only measure the internal stress of the glass qualitatively or semi-quantitatively according to the interference color sequence in the polarization field, but also accurately and quantitatively measure the internal stress of the glass. The value of the internal stress of the glass.

Features
Ø High-precision absolute angle encoder for measurement, the measurement accuracy is better than 2.0nm
Ø Dual numerical display on the LCD screen, which can simultaneously display the measured angle and optical path difference values
Ø The dark field does not need to be calibrated, and the user does not need to calibrate the zero point, which avoids the error caused by artificial calibration of the dark field.
Ø Green and energy-saving, using a more energy-saving and environmentally friendly LED light source, which saves more than 80% of energy compared to traditional light sources.
