Anti Reflection Nano-Coating in the Visible Range under the BK7 Glass Layer using a Lens

Applications

Lenses Photovoltaics

Properties

Nanostructured layers act as an effective medium in which incident light is diffracted off-axis resulting in increasing the average optical path length. This consequently allows the complete light absorption. FESEM results show a thickness less than 100 nm for nanolayers. Test results show a remarkable reduction in the light reflection after applying the coating.

Light scattering reduction Light transmission improvement

Manufacturer's Description

Antireflection coatings have been in use since long to overcome the problem due to Fresnel’s reflections, which significantly reduces the intensity of transmitted light. It is now established that the application of the multilayer nanocoating on the front surface of the photovoltaic cells or optoelectronic devices reduces the reflection of the incident light improving the device performance. The global value of optical coatings is estimated at $9.5 billion in 2016.
