Misunderstanding of optical lens film

Although optical lens manufacturers have accumulated a lot of professional knowledge in the industry, there are still some problems with regard to optical lens films. 

Now some people think that the broadband antireflection film should be green, not the green is not the broadband anti - film, these are misunderstandings, why the camera is higher than the aim mirror, no one is going to discuss the color of the film, but to see the reducibility of the image quality is the truth, the actual broadband antireflection film is more important regardless of the color. It is the high and low reflectance of its bandwidth, combined with high and low refractive index optical lenses, combined, and finally as far as possible to restore the color and brightness of the object, which is what we want to pursue.
