Polarization Axis Position Tester for Sun Glasses

Polarization Axis Position Tester for Sun Glasses

Production Introduction

The polarization axis tester is based on standards GB10810.3 and QB2659-2004 (the polarization direction test of polarizing lenses for motor vehicle drivers' special glasses requires the design of test instruments).

The instrument is to cut a pair of polarizers into the polarization direction and the horizontal direction of the Angle of ±3°, and then to form the upper and lower half of the polarizer of the viewing area. And fit on the glass plate to form the semi-shade polarizer, to measure the polarization direction of the lens, for measuring the axial deviation of the polarized lens.
