    The production of color

    The range of visible light is about 400-800 nm. If the light with the wavelength of 400-800nm is mixed evenly according to the appropriate proportion, and then it hits the retina of the eye, it will produce a white light sense. But why does matter show different colors? The first to reveal the secret of color is English scientist Newton. He used a prism to refract the sunlight twice. For the first time, he successfully decomposed it into seven color bands: red, orange, yellow, green, blue, blue ... read more

    Light source and color

    We are not unfamiliar with light, because we live in the world of light every day. All kinds of non luminous objects have bright colors. Only when enough light is shining, can we see them for people. All luminous objects can become light sources, while the sun is a huge natural light source and the only light source in the day for human beings. In fact, daylight light source is a natural light composed of direct light and reflected light in the sky, also known as overcast light.Automotive car li... read more

    The basic concept of color

    When we see an object, we first feel its color. The color of matter is visible to the human eye. If there is no light in the closed darkroom, or in the dark night, the color of the object is invisible. Only in light, the color of matter can be seen by the naked eye, so we say that color is produced by the interaction of light and eyes. In fact, color is the result of the brain's recognition of different kinds of light projected on the retina.Chrome Metallization Coating Machine Suppliers   ... read more

    frequently asked questions

    What is the reason for the difference of adsorption between vacuum evaporation and vacuum splashing?   Sputtering is a strong adsorption of positive and negative electrodes, so the adsorption of sputtering is more uniform, the density is greater, the hardness is greater, and the price of sputtering is 10% - 20% higher than that of evaporation.Plasma Coating Machine Manufacturers   Why can vacuum coating be made into different colors, and seven colors?   Because after the vacuum ev... read more

  • Vacuum sputtering

    Vacuum sputtering

    1, introduction   Usually refers to the magnetron sputtering, which belongs to the high-speed low-temperature sputtering method. Inert gas (AR) is filled in vacuum and high-voltage direct current is added between the cavity and the metal target (cathode). As the electron generated by glow discharge excites the inert gas to generate argon positive ion, the positive ion moves towards the cathode target at high speed, and the target atom is blasted out, and deposited on the plastic substrate t... read more
