Thin Films: AR Coatings

Coatings designed to reduce reflection loss, thereby effectively increasing transmission
Optimized for specific wavelength regions
Hard, scratch-resistant coatings
Applicable to various substrate materials (BK-7, fused silica, sapphire, etc.)

AR Coatings (400 to 700nm)

Residual reflectance < 0.45% on BK-7 glass
Residual reflectance < 0.30% on SF-11 glass
Wavelength Range from 400nm to 700nm
Other glass substrate materials comparable in refractive index can have AR coatings shown above

AR Coatings (400 to 850nm)

Residual reflectance < 0.35% on BK-7 glass
Wavelength Range from 400nm to 850nm
Other glass substrate materials comparable in refractive index can have AR coating shown above

AR Coatings (900 to 1700nm)

Residual reflectance < 0.75% on BAF2 glass Residual reflectance < 0.30% on BK-7 glass Wavelength Range from 900nm to 1700nm Other glass substrate materials comparable in refractive index can have AR coatings shown above

AR Coatings (900 to 1700nm)

Residual reflectance < 0.40% on fused silica (SiO2) glass Residual reflectance < 0.75% on Zinc Selenide glass Wavelength Range from 900nm to 1700nm Other glass substrate materials comparable in refractive index can have AR coatings shown above

AR Coatings (3000 to 5000nm)

Residual reflectance < 4% on Germanium glass
Residual reflectance < 4 % on Silicon glass
Wavelength Range from 3000nm to 5000nm
Other glass substrate materials comparable in refractive index can have AR coatings shown above

AR Coatings (6000 to 12000nm)

Residual reflectance < 6% on AMTIR glass
Wavelength Range from 6000nm to 12000nm
Other glass substrate materials comparable in refractive index can have AR coatings shown above

AR Coatings (Dual Band: 532/1064nm)

Residual reflectance < 0.1% on BK-7 glass
Wavelengths @ 532nm & 10640nm
Other glass substrate materials comparable in refractive index can have AR coatings shown above

DLC & Hard Coatings

Low loss, “hard” coating
Overcoats available for scratch resistance & durability
Applicable to various substrate materials (BK-7, fused silica, sapphire, etc.)
Common reflective metals used, such as gold, silver, and aluminum. Others available.
