WebOur wide-range birefringence measurement PA/WPA series systems provide high-speed birefringence measurement of transparent and semi-transparent materials, such as lenses and other transparent … Birefringence is used in many optical devices. Liquid-crystal displays, the most common sort of flat-panel display, cause their pixels to become lighter or darker through rotation of the polarization (circular birefringence) of linearly polarized light as viewed through a sheet polarizer at the screen's surface. Similarly, light modulators modulate the intensity of light through electrically induced birefringe…
WebCompared to conventional polarization imaging techniques, PS-FPM does not involve any mechanical rotation of the polarizer/analyzer and achieves birefringence imaging with a half-pitch resolution of 0.55 μm over 3.78 mm2 FoV, which corresponds to the space-bandwidth product of 12.5 megapixels.
