Optical Coating Market size was valued at $7,794 million in 2015, and is expected to grow at a CAGR of 6.6% to reach $12,351 million during the forecast period 2014 – 2022.
Optical coating is an amalgamation of thin layers of films that produce interference effects to improve transmission and reflection properties of an optical system. Coatings improve optical functions and protect the optic from extreme environmental conditions. These coatings are manufactured using metals, oxides, and rare earth materials.

The global optical coating market is segmented based on type, technology, end-use industry, and geography. Based on type of optical coating, the market is divided into antireflection, high reflection, transparent conductive, filter, beamsplitter, electrochromic, and partial reflection coatings. Technology-based classification includes vacuum deposition, E-beam evaporation technology, sputtering technology, and ion-assisted deposition technologies. By end-use industry, the market is divided into electronics & semiconductor, military & defense, automotive, construction, solar, and medical. Antireflective (AR) coatings reduce the multiple surface reflectance and enhance the transmission of light through the optical substrate. By eliminating the stray light, these coatings enhance the contrast of the image. They are majorly used in corrective lenses, camera lens, and solar cells.
