The PA6 is an advanced electronic device designed to verify the correct alignment of polarized lenses on sunglasses mounted on a headform.
It features an integrated polarization axis detection sensor for highly accurate and repeatable measurements. The device includes a special auto-calibration filter, which must be used at each startup to ensure precision.
The system is easy to use, with visual feedback during calibration and a clear LCD display showing settings and results.
Once calibrated, the eyewear is placed on dedicated supports, ensuring proper alignment of the lenses with the sensors. The automatic detection system is then activated via the display, and within seconds, the screen shows the test results.
The headform is designed according to ISO 18526-5 (size 1-M) and includes adjustable pantoscopic angle supports, helping streamline the testing process.
The PA6 is supplied with PC-compatible software for saving and managing measurement data.
It’s the ideal solution for eyewear manufacturers, and optical laboratories that require fast, accurate, and standardized testing of polarized sunglasses.
The polarization axis of a lens is the direction along which its polarizing filter lets light pass. This is a key element in the design of polarized lenses, which are usually oriented vertically—about 90° from the horizontal.
This vertical alignment helps block reflected light from flat surfaces like water, snow, or wet roads, significantly reducing glare.
According to ISO 12312-1:2022, the declared polarization axis must not deviate more than ±5° from the vertical (or from a specified direction, if different). The alignment between the left and right lenses in a pair of polarized glasses must not differ by more than 6°.
Our polarization axis testing tools help manufacturers ensuring their lenses meet international standards with precision and ease.
