Vacuum coating equipment glass lens coating knowledge

Basic knowledge of vacuum coating equipment glass lens coating, you know, there are no objects on the light reflection, this is the reason that we can see things. For the lens, in order to be able to make the light through the lens completely, in the film fully reflect the true nature of the situation, the best shot is through a variety of light completely. High-quality optical glass, which can reach 90% light transmittance

Above, the remaining light loss on the need of the lens surface coated film to compensate. Therefore, in the optical lens mainly antireflection coating plated also called AR coating. In order to meet various requirements, often require coated multilayer film. In order to improve scratch resistance of glass, the outermost layer tend to be high-hardness film. In the laboratory, modern technology can reach almost one hundred percent of light through. This is so because in actual use will be more or less affected by dust, dirt, etc. on the lens, making the reduction of light through the lens. Film in many ways, but also so several conventional methods.

The importance of coating equipment for coating thickness distribution

Vacuum coating electromechanical always want more evenly distributed coating equipment plating thickness on the workpiece, the better the deposition. When the total amount of metal deposited on the workpiece is the same, if the thickness is uneven, it will bring a lot of disadvantages:
(1) For the anodic coating, vacuum coating equipment can not stand at the expense of a thin ...coating of corrosion will first make the matrix rust. And a part of Corroded parts already failed, resulting in a waste of the coating is too thick at the metal. If it is to ensure the thinnest not rust, can only increase the average thickness, resulting in plating cost increases.

(2) to the cathode of the coating, vacuum coating equipment thin coatings at high porosity (see Part 10), it is easy to produce rust spots, and then increase the rust to form contiguous corrosion. Compared with the anodic coatings, cathodic corrosion coating thin place faster. For local seepage nitrogen, carburizing coating, easy to form thin at the hole, lose protection. If the thickness uniformity of the various parts of the porosity is not very different, the overall increase corrosion resistance. For example, the battery bright nickel plated steel rollers, housing (particularly by bottom place) coating is thin, even when washing and drying already starting small rust spots, yellowing, this should "the white" treatment, after rapid drying of water-soluble blocking agent.
(3) For the bright plating, vacuum coating equipment thin coating at the cathode current density due to small, so light leveling poor, affect the overall appearance.
(4) alloy electrodeposition, alloy composition is not the same at different thickness, or the appearance of uneven (such as imitation gold plating), and corrosion resistance are inconsistent or (such as zinc-nickel alloy).
(5) physical coating at different thicknesses, the mechanical properties (such as brittleness, internal stress, etc.) are not the same. If you would have to be plated after stamping molding machine processing, the coating is too thick at the often poor machining performance (peel, crack, powder off, etc.).
Terms of corrosion resistance, or appearance, machining performance perspective, both want to improve the uniformity of the coating thickness of vacuum coating equipment. For the size of the hard chrome plating, if the user requires no plating after grinding treatment, it is difficult to do; sometimes in order to ensure the thinnest reach the final size requirements, thickness uniformity is poor, have greatly increased the average thickness, which is in production are not uncommon. To make each part of the coating thickness on the workpiece as close as possible, we must understand the impact of thickness uniformity factor.

Glass coating, vacuum coating machine coating Notes

Automotive glass coating increasingly popular, but many people enjoy the convenience of just after the glass coating, maintenance coating film after the relevant considerations and has not been done, this effect is maintained for the coating is very unfavorable.

First, vacuum coating machine glass coating can be applied over the rearview mirror.

Because the mirror is not the wind, if the plating to allocate water glass drops then there will accumulate, thus affecting sight. Advanced car mirrors are hydrophilic glass. In fact, the general construction glass coating only the front windshield glass and other glass mirrors can also be construction but it is absolutely not the construction.

Second, anti-fog construction do not apply too thick.

Glass and glass coating agents typically used in conjunction with anti-fog, anti-fogging agent in glass at the time to pay attention not to apply too thick, too thick smear if they would not wipe clean. In addition, the duration of the anti-fogging agent with the weather, dry weather often duration, continuous rainy weather, then anti-fog effect is relatively short period of time, it is also important to note.

Third, posted proof membrane can still be coated.

Utility proof membrane is insulated privacy glass coating function is to increase the splash of the glass, these are two entirely different things, I do not know why anyone would think that the film will not be posted proof coating of. In fact, this is wrong, there is no proof membrane and coating affected. Proof membrane is usually attached to the glass inside, and coating agents and anti-fogging agent is generally used on the outside.

Fourth, do not rain or washing within four hours after the glass coating.

This is in order to better protect the car glass coating effect, rain or washing may affect the duration of the coating. And when coated glass has been cleaned, the coating process and will not stain the body, there is no need to wash after the film is completed. To avoid the rain, then simply choose the good weather to do a film on it.

Vacuum coating machine equipment vacuum drying process includes three processes. By the heat source to heat transfer to the material, make its heat and moisture vaporization, known as the heat transfer process. "Evaporation of moisture vapor migration to the drying room space, make the moisture vapor from the material surface and discharge drying chamber, the so-called material surface moisture vapor state mass transfer process.
Material internal moisture migration with liquid to the material surface, so that the surface evaporation, the so-called material internal moisture liquid mass transfer process. Visible, vacuum drying is accompanied by the three process and coordination, the coordination of good or bad, directly affect the quality of vacuum drying speed and its products.
Complete the heat and mass transfer process, the following three requirements must be met. Depending on the implementation of the heat transfer temperature difference between the heat source and material, provide materials with heating of the heat and moisture latent heat of vaporization, the so-called temperature condition. "Depend on the material surface and the moisture vapor pressure of drying chamber space to implement material moisture gas mass transfer, the so-called pressure (or vacuum) conditions, therefore must ensure that the moisture in the material on the surface of the steam pressure is higher than steam steam partial pressure of drying chamber space.
Depend on the material internal moisture moisture inside the material with the concentration of the liquid mass transfer, the so-called concentration condition. Optimization of the above three conditions and their combination can improve the quality of vacuum drying speed and its products.

The cause of the lens coating and methods

Lens coating, lens, or glass lenses, lamp lens are need coating appearance. Lens coating in fact, the reason is very simple, because the object has reflection effect on the light, because a lot of problems on the lens on the combination of the lens is impossible to let all light completely through various angles in theory, the light transmittance can reach more than 90%, the remaining 10% will be reflected out, form a glare. So you need to coating.
Lens coating in 1968 a new generation of coating technologies have been developed, coating process can be cheap and standard, coating lens is becoming more and more popular. Lens coating method, there are many on the market at present the most widely as one of the most popular coating method, physical vacuum coating method.
The latest way of physical coating technology, such as vacuum vapor deposition, ion plating a variety of different forms. The coating strength and uniformity generally higher than that of chemical coating. The past chemical coating, relative pollution is big, can't multilayer film plating. The latest vacuum coating to replace the chemical coating.
General coating layer on the surface of the lens itself is colorless, transparent, not only through the lens of the light will be reflected back, reflective visible to form the human eyes. Coating lens, the lens of the light transmittance is lower, reflections on the surface of the lens is more serious, therefore, each different camera lens, must according to the material used in the lens and the degree of absorption of different colours, plating on the different characteristics of the coating, mutual collocation, can increase the light transmittance of lens combined, and make the lens of light transmittance equilibrium.

Vacuum coating equipment and coated glass

Coated Glass (Reflective glass), also known as reflective glass. Coated glass is coated one or more layers of metal, alloy or metal compound film on the glass surface, to alter the optical properties of the glass, to meet certain requirements. Coated glass according to the different characteristics of the product, can be divided into the following categories: heat-reflective glass, Low-E glass, Low-E, conductive film glass.
Heat-reflective glass is usually coated on the glass surface layer or layers of thin films, such as chromium, titanium or stainless steel and other metals or compounds consisting of the product showed a rich color, appropriate for visible light transmittance, infrared has higher reflectance, the coated glass has a higher UV absorption rate, therefore, also known as solar control glass, mainly for building and glass curtain wall;
Low-E glass is coated on the glass surface of a multilayer thin-film of silver, copper or tin, or a compound consisting of a metal, the product has a high visible light transmittance, high infrared reflectivity, a good heat insulation performance, mainly used in construction and automotive, ships, and other transportation, due to poor film strength, are generally made using hollow glass; glass conductive film is a conductive film of indium tin oxide coated glass surface, etc., can be used for heating the glass defrost, defog and as liquid crystal displays..
Many coated glass production methods, the main vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition and sol - gel method. Magnetron sputter coated glass by magnetron sputtering techniques can be designed for producing a multilayer complex film system, a variety of colors can be coated on a white glass substrate, the film is preferably corrosion and wear resistance, is the production and use one of the largest product.

Watch glass coating and precautions

Any glass will have a reflective, including flat and have a curved glass, so, like many lens optical instruments (including glasses), the increase in order to reduce reflection and transmission ratio, you need to vacuum coating equipment to do the above in the glass coating processing. Especially glass diameter compare Japanese radian watches, need to increase the coating processing, can not completely eliminate the reflective coating, can only be reduced.

In the optical film material is currently available, a magnesium fluoride (MgF2) of refractive index of about the minimum, only 1.38, the magnesium fluoride coating can make use of light reflection rate of 4% to 1.8% while also increasing the transmission than, of course, in order to improve the transmission rate, it can also be used for multi-layer antireflection coating that both sides are coated inside and outside of the glass.

After the glass coating process above, will be showing a hint of violet color, typical is a camera or telescope lens, are usually treated with magnesium fluoride coating (MgF2), the refractive index of magnesium fluoride is 1.38, both much lower than the refractive index of ordinary glass, even lower than the sapphire glass (ordinary glass refractive index of 1.52, sapphire 1.76), where the higher the refractive index, the reflection is stronger. Therefore, the effect of the watch sapphire glass coating will be better after.

Some watches will create a flag to indicate that the watch glass is processed through the coating, such as Omega watches, the watch on the card or tag, with a circle inside a A letter to represent, while the AA said watch both inside and outside the glass coating on both sides. Originally reflex points on the watch, the more, including the case, dial, hands, not Guangcan gold, silver Guangcan is, therefore, the coating is more convenient to use one of the measures to wear watches, watch glass coating also does not like the camera lens Which obviously, some hard to see.

As noted in the information, magnesium fluoride (MgF2) crystal Mohs hardness of 6, is the general hardness, but because of the thickness of the thin film, so it is easy to be worn out. Common coating on the glasses are also very easy to be worn, this also depends on the specific use, such as glasses usually only add water wash detergent behind, we should be much longer than the direct use a cloth to wipe the hold time The watch glass is the same.

Coating the inside of the watch glass will not be worn when glass coating damage, there will be a careful look mottled pattern of cases, while attention is required, watches in the long-term storage under storage, be sure to pay attention to moisture, long time in the humid environment the glass surface will be moldy, but also undermines the coating layer.

Optional vacuum coating machine components of

For vacuum coating machine, the vacuum pump their access to essential part of every manufacturer of a coating machines are manufactured with one or more pumps.

First, the choice of the vacuum pump vacuum pump vibration when you first need to pay attention to when the work produced on the process and the existence of environmental impact, if the process is affected, or alternatively, anti-vibration measures should be taken to a vacuum pump. Choose the time you need to know to be pumping gas composition, selective evacuation if needed, may be insufficient to meet the requirements of a pump, the pump must be combined with a variety of different work with each other, if coater coating requires no oil will have to use no pump.

Second, the coating machine for extreme requirements and working pressure requirements of the greater degree of vacuum, the vacuum pump for higher capacity requirements, a minimum degree of vacuum pump ultimate vacuum equipment than half the number of working vacuum level and above.

Third, each pump has a certain working pressure range, such as diffusion pump pressure of 3 ~ 10-7mmHg, its stable working pressure range of 5 * 10-4 ~ 5 * 10-6mmHg, then not allow the use of a diffusion pump in addition to its work undecided working pressure range.

Higher four, when the gas pressure of the pump is not high demand or high degree of vacuum is not required, the priority selection in a single stage pump, through the exhaust gas pressure or vacuum requirements, single pump often can not meet the requirements, the choice of two pumps or multi-stage pumps.

Fifth, one of the key pump price and maintenance costs also need to be considered.
