Coated Molybdenum Target
Coating molybdenum target has good properties, including excellent high temperature performance, high temperature physical strength, high elastic modulus, excellent thermal conductivity and corrosion resistance and other properties, so commonly used in the field of coating, as coating materials. Its physical properties are as follows: melting point 2610 ℃, boiling point is 5560 ℃, the density is 10.2 g/cc, purity of 99.95%.
Coating, that is, when the light is passed into a different substance (such as the air enters the glass), there are about 5% light will be reflected away. In the holographic SIGHT and refractor can make incident ray loss rate to reach 30% ~ 40%. At the present optical lenses are usually coated with a single layer or multi-layer magnesium fluoride antireflection film. A single layer antireflection coating can reduce reflection to 1.5%and multilayer antireflection coatings can reduce reflection to 0.25%, so if the whole sighting telescope be coated, the light transmittance rate can reach to 95%. Coated with a single layer antireflection coating the lens is usually red or blue-purple, coated with multilayer antireflection film the lens is pale green or dark purple. Specific applications are as follows:
In the glass: Use in camera lens, myopia, hyperopia, reading glasses and other corrective glasses. Coated with very thin film on the surface can reduce light reflection, to increase light transmittance. Besides, it has excellent UV resistance and can also resist the light and ghosting. Different coating colors can make the image color balance different. In addition, coating on lens can also delay aging and discoloration time. Principle: The high voltage electron gun to gasify several drugs to make them uniformly distributed in the lens surface.
In the car: To apply coated molybdenum target in automobile paint beauty is the highest protection measure to avoid oxidation, which can make paint brightening, anti-acid, anti-oxidation, anti-UV and other multiple effects. What’s more the film is an inorganic material, so there is no damage to the car paint.
