Polarization Axis Position Tester for Sun Glasses

Detailed Product Description

The polarized lens is a lens manufactured according to the polarization principle of light, which is used to exclude and filter the direct light in the beam, so that the light can be put into the visual image of the eye on the light transmission axis of the right track, and the vision is clear and natural. It is mostly used for sunglasses and camera glasses.

In recent years, polarized sunglasses have become popular in the market. Polarized glasses have a function that ordinary sunglasses do not have, and this function can effectively block and filter out all kinds of stray light that are harmful to the eyes. The so-called stray light is the irregular reflection light generated when the light passes through the uneven road surface, water surface, etc., also called glare. When these rays of light directly irradiate people's eyes, it will make people's eyes feel uncomfortable and easily fatigued, cannot see objects for a long time, and the clarity of the objects they see is obviously not enough.

Sunglasses play an important role in people's life, but wearing a pair of unqualified sunglasses is very harmful.

Application:

This measuring instrument is designed for detecting the absorption axis angle of polarizing plate. It supports both single measurement and multiple continuous measurement .

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.

Features:

1. Measuring results display in real time;

available data management: data autosave, data query, data analysis , data report export;

2. Adopt extremely high-resolution imported motor, which ensures the measurement accuracy;

3. The sample carrier is automatically positioned during measurement. No additional human operation is needed. Thus guarantee high repeat accuracy;

4. Operators manually place the polarizing plate.
