Apple has introduced a "blue glass filter" since the iPhone 4/4S, greatly improving the quality of photography. Afterwards, whether it was Xiaomi 2 or Meizu MX2, high-end phones equipped with 8 million or more pixels began to popular back illuminated cameras with embedded blue glass filters. So, what is the purpose of this small blue glass and how effective is it during filming? Infrared light affects imaging quality. Firstly, we need to understand one thing
In order to meet the requirements of the geometric, optical, physical, and chemical properties of the filter, one or more layers of thin films with different properties and applications are often deposited on the surface of the component using chemical or other mechanisms in a vacuum environment. The commonly used filter films include anti reflective film, external reflective film, internal reflective film, spectral film, filter film, waterproof film, protective film, electric heating film, polarizing film, etc. The plating methods include solution precipitation, cathodic sputtering, acid etching, electrolysis or oxidation
UV Mirror - UV is actually an abbreviation for Ultraviolet Rays in English: for shooting, no filter should be the best. Especially when facing a light source, the glare caused by UV mirrors will definitely affect the image. The purpose of coating is to minimize the generation of glare as much as possible. Multi layer coating UV means coating 6-8 layers of film on each side of the lens to ensure a transmittance of over 95%. So it is recommended to purchase UV lenses with higher transmittance
