Method and device for testing polarizers

摘要

A polarizer testing device and method thereof, wherein the polarizer testing device comprises: a monochromatic light source capable of providing a monochromatic light; a light detecting module arranged according to the monochromatic light source capable of converting the light signal of the monochromatic light source into readable data; an adjustable base arranged between the monochromatic light source and the light detecting module capable of supporting a polarizer for testing and fine tuning the angle of the polarizer for testing, wherein the monochromatic light is detected by the light detecting module after passing through the polarizer for testing. A stationary base can be further arranged in the polarizer testing device, which the stationary base is arranged between the monochromatic light source and the adjustable base capable of supporting a polarized polarizer for the light to pass through to form a polarized light.
