If you want to decide whether to use AG glass or anti-reflective glass, you can judge from the following aspects to determine whether AG glass or AR glass is more appropriate.

Transmittance: If the transmittance of the terminal product to the glass cover plate is more than 93%, basically need to be plated AR plating to corresponding. Float AG glass is generally 88%~91%, glass after etching AG can almost reach about 93%. After AG coating, the highest glass can reach 98.5~99%.

Product cost: The specific product depends on the market positioning and target customer groups, and some customers use the combination of AG glass +AR coating to achieve product functions, such as some automotive center control touch screen or display equipment has such a design process. Generally speaking, AG glass and anti-reflective glass are more than 50% higher than the cost of a piece of smooth glass because the glass itself is difficult to process and industrial processing technology and so on. Therefore, whether to use AG glass or AR glass or depends on the needs of the product itself.

Size: AG glass and anti-reflective glass will be limited by processing size, affecting the quality and cost of glass. At present, AG glass can be processed in a wider range of sizes for the same cost. At present, the AR glass processing technology with the best quality or durability is mainly vacuum sputtering, which determines the size of the glass cover plate can not be too large. However, in small sizes, especially those similar to the size of camera lens protective cover glass, we believe that the use of anti-reflective glass is more beneficial.
Strengthening conditions: anti-reflective glass is basically after strengthening and then coating, basically in the finished product state surface treatment. AG glass, on the other hand, is treated at the original stage, then chemically strengthened and physically strengthened after the shape is processed, and finally screened on the surface.
