Question

What is antireflection coating? What is its application?

Answer 1

Answer:

Antireflection coatings minimize the reflection of one or many wavelengths and are typically used on the surface of lenses so that less light is lost. A simple coating can be designed to minimize the reflection on an interface between two materials by providing an extra material for light to interact with.

Answer 2

$\Huge{\boxed{\mathbb{\fcolorbox{black}{pink}{HELLO\:!!!}}}}$

An antireflective or anti-reflection coating is a type of optical coating applied to the surface of lenses and other optical elements to reduce reflection. In typical imaging systems, this improves the efficiency since less light is lost due to reflection.

Antireflection (AR) coatings are widely used in various applications such as display panels, solar cells and, optical lenses. AR coatings are usually applied to glass surfaces, but in many applications the glass substrates are being replaced with polymers.
