| Résumé : |
An optical coating is one or more thin layers of material deposited on an optical component such as a lens or, mirror, which alters the way in which the optic (Glass ) reflects and transmits light. One of the types of optical coating is an antireflection coating, which reduces unwanted reflections from surfaces.
As light passes through an uncoated glass substrate, approximately 4% will be reflected at each interface. This results in a total transmission of only 92% of the incident light. Applying an AR coating on each surface will increase the throughput of the system and reduce hazards caused by reflections traveling backwards through the system (e.g. ghost images).
Antireflection (AR) coatings have been widely employed in optical and optoelectronic materials, a decrease in light reflection, and thus an increase in the transmittance of light, enables clear viewing with the eyes of glass and displaying surfaces. AR coatings find its application to Image sensors, Lithograph; Light-emitting diodes (LEDs) are a common solid state light source. Also in camera lenses, Solar panels etc where loss of light by reflection is the loss of output and quality of the product.
The principle of AR coating is based on the destructive interference of reflected light from interfaces between air and a film. |
