Crystalline coatings (or crystalline mirrors [1]) are a type of thin-film optical interference coating that is made by merging monocrystalline multilayers deposited via processes such as molecular-beam epitaxy (MBE) and metalorganic vapour-phase epitaxy (MOVPE) with microfabrication techniques including direct bonding and selective etching.
Factory tint", done at the time of manufacture is generally not an applied film, but instead is done by dyeing the inside of the glass with a darkened pigment during glass manufacturing, an electrical process known as "deep dipping." The pigment gives the glass a tint, but doesn't provide UV ray protection or heat rejection like most window ...
In manufacturing high-quality composite parts, such as in the aerospace industry, FEP film can be used to protect parts during the curing process. In such applications, the film is called "release film" and is intended to prevent the curing adhesive polymer (e.g. the epoxy in a carbon fibre/epoxy composite laminate) from bonding to the vacuum ...

Edge-defined film-fed growth or EFG was developed for sapphire growth in the late 1960s by Harold LaBelle and A. Mlavsky at Tyco Industries. [4] A shaper (also referred to as a die) having dimensions approximately equal to the crystal to be grown rests above the surface of the melt which is contained in a crucible .
Paint protection films use by the military has continued to the present day and 3M now makes a wide variety of aerospace and military films. [3] With time, however, the automobile industry began to take note of the protective benefits of PPF and it was soon being employed by race car drivers despite the difficulty of working with the original films.
Another type of crystallization occurs upon extrusion used in making fibers and films. In this process, the polymer is forced through, e.g., a nozzle that creates tensile stress which partially aligns its molecules. Such alignment can be considered as crystallization, and it affects the material properties.
Glasses (non-crystalline ceramics) also are used widely as host materials for lasers. Relative to crystalline lasers, they offer improved flexibility in size and shape and may be readily manufactured as large, homogeneous, isotropic solids with excellent optical properties.
