>< /> :r= d Magnesium fluoride M anti-reflective film.% high transmittance film
How much does magnesium fluoride M anti-reflective film.% high transmittance film cost? This question has caused doubts in quite a few people! With the rapid development of the mobile Internet, high-power laser anti-reflection film manufacturers are also booming, and anti-reflection film development companies are springing up like mushrooms after a rain. Their technical strength and after-sales service vary widely. Since the year, the excellent anti-reflective film technology of the Soguang Thin Film Technology Research Center has been widely welcomed by the market. As a product with stable products and excellent technology in the industry, the last special reminder is: before choosing an anti-reflective film developer However, do not cooperate with irregular developers just to get cheaper prices. This approach will only damage your own interests. Cooperating with regular developers can reduce a lot of unnecessary troubles, and at the same time ensure a long-term, good and sustainable cooperative relationship in the future. If you have any needs, please contact us. We are direct sales from the manufacturer. Contact number:, mobile phone, thank you Ms.:
Anti-reflection coating is also called anti-reflection coating, R film, R film, anti-reflection film, R filter. Its main function is to reduce or eliminate the reflected light from optical surfaces such as lenses, prisms, and plane mirrors. This increases the amount of light transmitted through these components and reduces or eliminates stray light in the system. The simplest anti-reflection coating is a single-layer film, which is a thin film with a low refractive index coated on the optical surface of optical parts. If the optical thickness of the film layer is one quarter of a certain wavelength, the optical path difference between two adjacent beams of light is exactly , that is, the vibration directions are opposite, and the superposition result reduces the reflected light of that wavelength from the optical surface. By appropriately selecting the refractive index of the film, the reflected light from the optical surface can be completely eliminated. Under normal circumstances, it is difficult to achieve the ideal anti-reflection effect with a single layer of anti-reflection coating. In order to achieve zero reflection at a single wavelength or to achieve a good anti-reflection effect in a wider spectral area, double layers, three layers or even more are often used. Multi-layer anti-reflective coating. Anti-reflection film is the most widely used optical film with the largest output. Therefore, it is still an important research topic in optical film technology. The focus of research is to find new materials, design new film systems, improve deposition processes, and make By using the least number of layers and the simplest and most stable process, we can obtain the highest possible yield and achieve the most ideal effect. For laser films, anti-reflection coatings are the weakest link in laser damage. How to improve its damage intensity is also one of the most concerning issues.
Light has wave-particle duality, that is, from a microscopic perspective, it can be understood as a wave and as a bunch of particles moving at high speed (note, please do not understand it as a simple Waves and a simple particle. They are all microscopic. The wavelength of red light wave =.micron. The wavelength of purple light =.micron. And the mass of a photon is.kilogram. So it seems that they are far from what we think. Think of the kind of macroscopic waves and particles.) The principle of anti-reflection coating is to consider light as a wave, because light waves also have the property of interference like mechanical waves.
Apply an anti-reflection coating (usually calcium fluoride, slightly soluble in water) in front of the lens. If the thickness of the film is equal to the red light (note: it is red light here), the wavelength in the anti-reflection coating A quarter of the time, then the red light reflected on both sides of the film will interfere and cancel each other out. You will not see any reflection in front of the lens because this beam of red light has already passed through the lens. .
Why have I never seen a lens without reflection? The reason is very simple, because visible light has seven colors: red, orange, yellow, green, blue, indigo, and violet, and the thickness of the film is unique, so It can only allow one color of light to completely enter the lens. Generally, all green light is allowed to enter. In this case, the color of the lens reflection you see in visible light is blue-purple, because this reflection There was no green light left in the light. The thickness of the film can also be determined based on the color characteristics of the lens.
