  Optical lenses are widely used in many systems such as laser systems, medical systems, and industrial systems. In the high-tech field, we can often see the existence of optical lenses. We also clearly understand that the light transmittance of optical lenses is an important factor in use. Performance, and now that the optical lens can increase its light transmittance, and the low-cost process is undoubtedly the coating process. The anti-reflection function of the optical lens is realized by an automated AR plasma spray coating machine.

The principle of optical lens antireflection coating process

  The rapid development of optical lenses is closely related to the development trend of optical lenses. New reforms and innovations of optical components usually put forward new regulations on optical lenses, thereby promoting the development trend of optical lenses. With the continuous development and scientific research of anti-reflection coatings, the plating technology of electro-optical anti-reflection coatings is also constantly developing. The wall thickness of the electron optical antireflection coating should be adjusted to 1/4 of the wavelength of visible light, and the uniformity requirements of the antireflection coating are also very strict. Even so, in our persistent exploration, Seismic has mastered many practical and excellent coating technologies.

  Anti-reflection film, also known as anti-reflection film or AR anti-reflection film (scattering-increasing optical lens or anti-reflection surface optical lens), is a lens coating that is specially treated on the surface of optical lens to increase the transmittance of optical lens, which is stacked on optoelectronic devices Surface, to reduce the surface reflection surface, improve the transmittance of optical elements of the optical film. The working band can be divided into single wavelength, multi-wavelength and broadband network AR coating, from extreme ultraviolet area to far infrared area.

  It can be seen that the role of the anti-reflection coating is to reduce the intensity of the reflected surface light, thereby increasing the intensity of the scattered light, and making the optical components appear clearer. The basic principle is to use the actual effect of the intervention of different optical lens films to remove the incident angle and refracted light, thereby increasing the light transmittance. There are two processing techniques: single-layer surface coating and two-layer surface coating. Optical lenses coated with single-layer anti-reflection coating are generally purple-blue or bright red, and optical lenses coated with double-layer anti-reflection coating are light green or purple-red.

  The above is about the principle of optical lens using anti-reflection coating technology, which can improve the performance of optical lens. The automatic AR plasma spray coating machine of Seismic Co., Ltd. is used to realize the anti-reflection function of optical lens, which can make the optical lens of optical lens. Performance reaches the level of use in special industries. At the same time, it has also helped many optical lens manufacturers to enhance a major market advantage, with low coating cost, high efficiency and good production capacity. The use of antireflection coating technology for optical lenses can greatly enhance the competitiveness of enterprises.
