7 Important Properties Of AG Glass
There are 7 important properties of AG(anti-glare) glass , Gloss,Haze,Transmittance,Thickness,Roughness,Granularity and Distinctness.
1. Ag Glass parameters - Gloss:
The so-called glossiness indicates the degree to which the surface of an object is close to a mirror surface. The higher the glossiness, the closer the glass surface is to a mirror surface. The main purpose of AG glass is to prevent glare, and the main principle of anti-glare is diffuse reflection. The main indicator for measuring diffuse reflection is glossiness.

2. AG glass parameters - haze
Haze is the percentage of the transmitted light intensity that deviates from the incident light by more than 2.5° to the total transmitted light intensity, which is an important parameter for the optical transparency of transparent or translucent materials. The greater the haze, the lower the gloss and transparency of the film, especially the imaging degree. The cloudy or turbid appearance of the interior or surface of a transparent or translucent material caused by light diffusion.

3. AG glass parameters - transmittance
In the process of incident light passing through the glass, the ratio of the light projected and transmitted through the glass to the projected light is called transmittance. Generally, transmittance has a lot to do with the properties of the material. The transmittance of AG glass is closely related to the glossiness value. The higher the glossiness, the higher the transmittance value, but it cannot exceed 92%.

4.AG glass parameters - thickness
Thickness refers to the distance between the upper and lower opposite surfaces of the glass. Refers to the thickness of an object. The symbol "T" is in mm. The thickness of the AG finished product is based on the customer's requirements for the thickness of the AG finished product and provides various parameters. Our company evaluates whether it is achieved according to the parameter requirements. After the evaluation, it is necessary to make a sample test piece, measure the parameters and thickness, and then give the correct thickness tolerance.

5.AG glass parameters - roughness
Roughness (Ra), a mechanical term. In mechanics, roughness refers to the microscopic geometric shape characteristics composed of small spacing and peaks and valleys on the processed surface. It is one of the issues in interchangeability research. Surface roughness is generally formed by the processing method used and other factors. The function of the part surface is different, and the required surface roughness parameter value is also different. The surface roughness symbol should be marked on the part drawing to illustrate the surface characteristics that must be achieved after the surface is completed.

6.AG glass parameters - Granularity
AG glass span is the diameter of the surface particles after glass etching. We can use the equipment to observe the AG glass particles to see the particle shape more intuitively. In addition, by connecting the Display Screen, the enlarged image of the AG glass surface particles is displayed on the display screen, and the size of the particle span is tested by software tools (generally in microns). Through the image, observe whether the particle span of the AG glass surface is uniform.

7.AG glass parameters - distinctness
Distinctness of image is also called image clarity and projection clarity. Glass clarity is generally related to the particle span index. The smaller the particles, the lower the span, the larger the pixel density value, and the higher the clarity; the surface particles of AG glass are like pixels. The finer and more numerous, the higher the clarity. Detailed explanation of distinctness》
