As an indispensable material in modern architecture, transportation vehicles, and optical equipment, the light transmittance of glass directly affects the product's performance and energy-saving level. With the development of science and technology, people's requirements for the light transmittance of glass are constantly increasing, especially in green buildings, solar energy utilization, and high-end display equipment. Improving the light transmittance of glass has become a key technology. So, how does glass improve its light transmittance?



Firstly, from the perspective of material selection, low-iron glass is one of the important means to improve light transmittance. Ordinary glass contains a large number of trivalent iron ions, which absorb part of the visible light, causing the glass to appear light green and reducing the light transmittance. Low-iron glass, by reducing the iron content, significantly improves the transmittance of visible light, up to 91% or more.



Secondly, surface treatment technology is also a key factor in improving the light transmittance of glass. Common anti-reflective (AR) coating technology can form a layer or multiple layers of films with specific refractive indices on the glass surface, thereby reducing light reflection losses at the interface. This technology is widely used in display screens, solar panels, and eyeglass lenses, effectively improving the light transmittance while reducing glare.







In recent years, the development of nanoscale surface technology has provided new ideas for improving the light transmittance of glass. For example, by laser etching or chemical etching to create nanoscale structures on the glass surface, the effects of



Finally, environmental factors such as the cleanliness of glass and the angle of use will also affect the actual light transmittance. Regularly cleaning the glass surface to avoid the accumulation of dust and stains helps maintain its optimal light transmittance; and designing the installation angle of glass reasonably also helps maximize the utilization of natural light.



In summary, improving the light transmittance of glass not only depends on the optimization of the material itself, but also involves advanced processing technology and surface treatment techniques. In the future, with the continuous emergence of new materials and technologies, the light transmittance of glass will continue to improve, bringing greater development space to fields such as energy conservation and environmental protection, intelligent display, and the utilization of new energy.
