At present, there are more than 60 kinds of common varieties of optical coating materials, and their varieties and application functions are still being continuously developed. In recent years, it has developed into metal film system, when the thickness of gold, silver, copper and aluminum is 7 ~ At 20um, its transmittance to visible light is 50%, while that of infrared light is less than 10%. This kind of thin film has been Feliciter applicantur ad panel Apollo spatii ad transmittendum pars visibilis lux, et fere omnes ultrarubrum lucis reflectitur pro scelerisque imperium {{VII}} De his articuli maxime inducit ad rationem, {VIII}}
Ego . Definitio de optical amet
Optical film est quaedam optical medium materia, quae est composito ex tenui medium et propagat lucem trabem per interface . {{II}} {{{}} {{{}}
The definition of optical film is: the thin and even dielectric film layer attached to the surface of the optical device in the process of light propagation path, the reflection, penetration (folding) when passing through the layered dielectric film layer) characteristics such as emission and polarization, so as to achieve the special forms of light that we want in one or more wave bands, such as all the light passing through or all the light reflection or polarization Aeternum .
Optical film est ubique in vita, ex praecisione et optical apparatu, ostentationem apparatu ad applicationem optical film in cotidiana vita; Exempli gratia, specula, digital cameras, omnes de familia appliances confectus ad Ordinarius tempora, aut anti-counterfactum technology in banknotes potest vocari, ut ex initiatorum technology et progressionem, quod etiam ostendit in elit, {{II}, qui etiam ostendit in libero technology, {II}
Optical film refers to the coating vel coating de uno vel layers of Dielectric film aut metallum film aut compositum ex his duabus genera films in optical elementa vel independens ad mutare ad transmissionem et phase et lumen {{{Polarization et per propriis in modum, in diversis fluctus et reflectivity vincula potest esse adaequatum, et lux in diversis polarization plana potest etiam diversis characteres {{I}}
Generaliter loquendo, productio modi optical tenuis films sunt maxime dividitur in sicco processus et infectum processus . in toto processus in gas est ad perficiendum est in superficie, in solidum, in auro, quod est ad usum, {}}} metallic packaging film for decoration seen in daily life is a product made by dry coating. However, considering the actual mass production, the application range of dry coating is smaller than that of wet coating. The general method of wet coating is to mix components with various functions into liquid coating, and apply them on the base material in different processing methods, then dry and solidify the liquid coating to make the product.
II {. principium tenui film intercessiones
{1. et fluctuatione lux
In 1860s, American Physicist Maxwell developed in electromagnetic doctrina, demonstrando quod lux est quaedam electro fluctus, quod facit undam doctrina develop ad perfectum gradu {{I}}
Secundum Bo Li Duality lucis, lux est idem quod radio fluctus, X radii ,? Radii sunt electromagnetic fluctus, sed eorum frequentiis sunt diversis {{I}} in relatione in intus λ, frequency u et propagationem Rate V electro fluctus est ut sequitur:
V = λ u
Since the propagation speed of electromagnetic waves of various frequencies in vacuum is equal in Germany, the wavelength of electromagnetic waves with different frequencies is also different. The wavelength with high frequency is short, while the wavelength with low frequency is long. For the convenience of comparison, according to radio wave, infrared ray, visible light, ultraviolet ray, X-radius et? Et adsum (vel frequency) de radiis, etc, {{III}}, disponere eos in spectro in ordine, quod dicitur electro spectro {{{}}
In electro spectro, radio fluctus habent longissimum adsum, quod potest dividat in longum unda, medium undam, brevis fluctus, fluctuum, {{I}, videri per humanum, solum visibilis lumen, quod est in humano} oculis {{{II}} Introdi visibilis lux est de 0 {{V}} LXXVI microns ad 0 {{VII}} XL microns, quod tantum rationum ad parva pars electro spectro {{VIII}}} Secundum est X-ray. Et electromagnetic fluctus cum brevissimo fluvialem est y ray.

, 2. Tenues film intercessiones
The film can be a transparent solid, liquid or a thin layer of gas clamped by two pieces of glass. The first beam of light is reflected by the upper surface of the film, the refracted light is reflected by the lower surface of the film, and the second beam is reflected by the upper surface. The two beams are on the same side of the film, separated from the same incident vibration, it is coherent light and belongs to amplitude interference. If the light source is an extended light source (surface light source), interference can only be observed in the specific overlapping area of two-phase dry beams, so it belongs to localized interference. For the planar films whose two surfaces are parallel to each other, the interference fringe is located at infinity, which is usually observed in the focal plane of the image by means of convergent lens; Nam cuneum informibus films, intercessiones fimbriis localization est prope film {{VI}}
Et experimenta et in rebus probaverunt, quod solum cum duo columnas de lumine fluctus habent quaedam necessitudo potest intercessiones verberibus generantur .} et siccis, frequency in duas fluctus}}; Vibrationis directionem duae fluctus eadem; Et Phase differentia inter duas lux fluctus permanet assidue {{II}}
Optical semita differentia formula duo-tempus arida lux intercessit tenuis film est:
Δ=ntcos () ± λ / II
In formula, n est refractivam index de film; T est crassitudo in film ad incident punctum; Est Refractione angulus in film; λ/2 is because two beams of coherent light are at two interfaces with different properties (one is optical density medium to optical density medium, the other is optical density medium to optical density medium) additional optical path difference caused by upper reflection. The principle of thin film interference is widely used in the inspection of optical surface, precise measurement of tiny angle or linearity, preparation of Antireflection film et intercessiones filter, etc, {II}}
The light is radiated by the change of the motion state of the original atom or molecule in the light source. The light wave emitted by each atom or molecule is only a short column, the duration is about 1 billion seconds. For two independent light sources, it is not easy to meet the three conditions of interference, such as the same phase or constant phase difference in special markets, therefore, two independent general light sources cannot form A cohaerens lux fonte {{III}} Et etiam lumen emittitur per diversas partes eiusdem lucis fonte non intermixti, quia sunt emittitur a diversis atomis vel moleculis {{IV}}

People always choose metals with large extinction coefficient and stable optical properties as metal film materials. The metal thin material commonly used in the ultraviolet region is aluminum, the aluminum and silver are commonly used in the visible region, and the gold, silver and copper are commonly used in the infrared region. In addition, chromium and platinum are also often used as membrane materials Nam aliquam specialem films {{VI}} quia aluminium, argentum, aeris et aliis materiae sunt facile ad oxidize in aere et reducere eorum perficientur, ut sit protected per electrica defensiva membranam includit Silicon}}, Magnesium, et Silicon Dioxide, Aluminium Membra Fluoride {{VIII}}
