Detection tool and detection method for light transmission angle of optical material

The invention discloses a detection tool for a light transmission angle of an optical material in the field of light transmission angle detection of the optical material. The detection tool comprises a fixed plate, a plurality of polarizers with different light transmission angles and a plurality of pieces of angle label paper, wherein the fixing plates are transparent hard plates, a plurality of polarizers are arranged between a pair of fixing plates, and the pair of fixing plates are adhered through an adhesive; the label paper with different angles is marked with different angle values and is arranged on one side of the polaroid with the same light transmission angle value; whether a light transmitting angle of the polaroid is qualified or not can be conveniently detected, and whether the optical film in the manufactured optical film assembly is reversely placed or not can be judged. 本发明公开了光学材料透光角度检测领域的一种光学材料透光角度的检测工装，检测工装包括固定板、多个不同透光角度的偏光片和多个角度标签纸；固定板为透明硬质板，多个偏光片设置在一对固定板之间，并且，一对固定板通过粘接物粘接；不同的角度标签纸标记有不同的角度
