What is Dielectric Mirrors?
A dielectric mirror, also known as a Bragg
mirror, is a type of mirror composed of multiple
thin layers of dielectric material, typically
deposited on a substrate of glass or some other
optical material. By careful choice of the type
and thickness of the dielectric layers, one can
design an optical coating with specified
reflectivity at different wavelengths of light.
Dielectric mirrors are also used to produce
ultra-high reflectivity mirrors values of
99.999 or better over a narrow range of
wavelengths can be produced using special
techniques. Alternatively, they can be made to
reflect a broad spectrum of light, such as the
entire visible range or the spectrum of the
Ti-sapphire laser.

How Do You Choose The Best Dielectric Mirrors?
Mirrors are an essential tool in any laser system
as they are used for beam steering and sampling
or for delivery of pump and alignment lasers. A
high-performance mirror needs to have low
scatter, high efficiency and excellent
durability. Often in conjunction with high laser
damage threshold, Dielectric Mirrors make their
way to be the best quality mirrors. Choosing a
mirror requires first identifying the wavelength
and bandwidth required at which point more than
one type of coating may be offered.

Keep In Mind These Pointers While Buying
Dielectric Mirrors

• This is typically made with one of the few
  materials with suitable optical properties like
  silver, gold, aluminum or chrome.
• In the design of dielectric glasses, an optical
  transfer-matrix method can be used. These mirror
  coatings are ideal for applications that require
  maximum reflection over a specific wavelength
  region.
• The method is to apply the amount of the metal to
  achieve the amount of reflection required for the
  mirror and it is used for creating Dielectric
  mirrors. Typically done using alternating layers
  of a conductive material like ZrO2, TiO2, Ta2O3
  or HfO2, it also uses an insulator such as SiO2
  or MgF2.
• If you are not a big fan of wearing eye glasses
  but had to wear glasses, remember to choose
  dielectric mirrors which has cool frames.

• These mirrors are made of dielectric material
  which can shield your eyes from all the dust and
  sun and at the same time work the specialize
  treatment you are going through too. These are
  based on the interference of light reflected from
  the different layers of dielectric stack.
• Simple dielectric glasses functions with
  one-dimensional photonic crystals, consisting
  stack of layers with a high refractive index
  interleaved with layers of a low refractive
  index.
• When a metal mirror is made, a thin layer of SiO2
  is typically applied to it so that the
  antifouling compound can permanently bond to the
  coating. This gives the appearance that the
  coating is a dielectric.
• Dielectric coatings in mirrors are manufactured
  below 60C for direct deposition onto fiber optic
  devices. These offer fibers ends, laser diodes,
  rod lenses, laser bars and other temperature
  sensitive components.
• Simple dielectric mirrors functions with
  one-dimensional photonic crystals, consisting
  stack of layers with a high refractive index
  interleaved with layers of a low refractive index.
