Description

Technical Field

[0001] The utility model relates to the technical field of glasses calibration equipment, in particular to a polarization axis calibration light box. Background Art

[0002] With the development of resin glasses, polarized glasses are widely popular as a functional type of resin glasses, and polarized glasses are essential equipment for some outdoor sports, such as skiing and fishing. Polarized glasses can effectively filter out scattered light in the light beam, avoid glare and glare, make the vision clear and natural, and the scenery looks soft and not dazzling.

[0003] Deficiencies of existing technology:

[0004] At present, the polarization axis of the polarizing film is in the vertical direction. After the reflected light of the object enters and passes through the polarizing film, the vibration perpendicular to the polarizing axis is filtered, and the vibration parallel to the axis passes, and the balance between the two is weakened. During the assembly process of polarized lenses with refractive power, the axis is an important indicator to measure the function of polarized glasses. If the polarizing axis deviates from the vertical angle by more than 10°, it will seriously affect its function. Therefore, during the production process of polarized glasses, it is necessary to ensure that the reference line of the polarizing axis must be controlled within ±3° of the vertical angle to ensure that the reference line of the lens remains parallel to the geometric horizontal line of the frame during subsequent processing.
