V-7000 series polarizer evaluation system

Polarizer is a typical optical device which has been used for such several purposes as polarized sunglasses, polarized filter, display part of electronics instruments. Typical example of the display part of electronics is liquid crystal display. With innovation for higher quality of these high technology products, much higher accuracy have been required for quality control of the polarizer to evaluate optical characteristic or color design. Liquid crystal display industry is especially proceeding to achieve higher quality of display, and it is now getting very important to evaluate shielding capability more precisely on condition that polarized prisms are in crossed-Nicol status.

In this technical note, the most suitable system for precise measurement of such polarizer will be explained.
