antireflective的意思|示意

Antireflective(AR) coatings is an important optical component, which is widely used in optical industry. It uses an optical coating to reduce reflection at the surface of a lens or optical component and increase the light transmittance.

AR coatings can be used for various applications. For instance, it can be used in spectacle lenses to reduce the glare from sunlight, enhance contrast and provide comfortable wear. It can also be used in solar cells to reduce light reflection and increase its efficiency. In addition, AR coating can be applied to lenses for cameras and telescopes to reduce the reflection of light and improve the contrast of the images.

AR coatings are usually made from dielectric materials, such as titanium dioxide, magnesium fluoride and zinc sulphide. They are most often applied as a multilayered coating to the surface of the lens or optical component. Each layer has different optical properties, which are determined by its refractive index. With the combination of these layers, reflection of light can be minimized.

In conclusion, AR coating is an important optical component which is widely used in optical industry. It can be used to reduce reflection of light, improve contrast, enhance efficiency of solar cells and provide comfortable wear.
