Infrared Antireflective Film
Our Antireflection film is an optical coating with a wide range of applications, which is widely used for TV, industry, astronomy, military science, and other fields.
The antireflection film, also known as antireflection film, its the main function to reduce or eliminating the reflected light of optical surfaces such as lenses, prisms, and plane mirrors, to increase the light transmission of these elements, and reduce or eliminate the stray light of the system.
Antireflection film is an optical film with the widest application and the largest output. Therefore, it is still an important research topic in optical film technology. The focus of the research is to find new materials, design new film systems, improve the deposition process, use the minimum number of layers, the simplest and most stable process, obtain the highest yield possible, and achieve the best effect.
Infrared Antireflection film is suitable for a variety of infrared system applications, including infrared thermal imaging, infrared detection, CO2 laser system, etc. we can provide Infrared Antireflection film in 8-14um, 10.6um, and other bands. The film has the advantages of low reflectivity, high transmittance, firm film, good finish, small absorption, and stable and reliable performance.
Basis of the antireflection film
Fluctuation and interference of light
The principle of this phenomenon is that when two light waves with the same amplitude and wavelength are superimposed, the light wave amplitude is enhanced; The superposition of two light waves with the same amplitude and different wave paths cancels each other. The antireflection film plated on the surface of the lens uses this principle to make the reflected light produced on the front and rear surfaces of the film interfere with each other, to offset the reflected light and achieve the effect of antireflection.
Application of antireflection film
Antireflection film is an optical coating with a wide range of applications, which is widely used in daily life, industry, astronomy, military science, electronics, and other fields. With the development of the electronic industry and computers, anti-glare and anti-static film for display and computer video screens have become new application fields of antireflection film, which has broad market prospects. It can not only effectively improve the conversion efficiency of the battery, but also improve the mechanical, electrical, optical, and other physical and chemical properties of the matrix.
Application in solar cells
Silicon material is a kind of semiconductor material. The principle of solar cell power generation is mainly to use the photoelectric effect of this semiconductor. The refractive index of silicon is very large, and the light shining on the silicon surface cannot be fully absorbed, but a large part of it is reflected. To minimize the reflection loss, one or more layers of antireflection film with refractive index and thickness matching the battery can be plated on the battery to improve the conversion efficiency of the battery.
The over-plating antireflection film can increase the transmittance of light, to improve the efficiency of the battery. Porous silicon dioxide antireflection film can not only improve the conversion efficiency of the battery by 5% - 6% but also improve the crack resistance of the matrix; Silicon nitride antireflection film can improve the conversion efficiency of the battery to 16.7%. The film has good compactness and can passivate the defects on the surface of a silicon wafer; Titanium dioxide and zirconia antireflection films can improve the alkali resistance and water and moisture resistance of glass matrix.
