Little knowledge of optical lens
1、 Index
We have lenses with different indexes, CR39 1.499, 1.56, 1.6, 1.67, 1.74, PC 1.59. It’s definitely not that, higher index, the better. Generally higher index, higher ABBE value, and lower definition. It means, when rays deflect when go through the lens, the eyes work harder to restore the objects. That’s why high index lens is not comfortable for some people.
Of cause, higher index make lens thinner. Your nose and ears will be greatly appreciated. And it looks more beautiful.
2、 Spherical (SP) and Aspherical (ASP)
Comparing with Spherical lens, Asperical lens increases the light variation from the edge, to improve the imaging quality.
The spherical aberration, caused by rays of different waves, which hit different positions of lens and don’t drive to one focus, will affect the imaging quality.
3、 UV VALUE
UV, is called “Ultraviolet rays”. Usually UV value of lens is set to UV360, UV380, UV400, UV420, named absorbable the longest light band. Although UV causes some damage to eyes, we have to choose the value according to the strength in different area. The lens goes more yellowish with high UV value, causes color difference of the imaging as well.
To eliminate the difference, it costs a lot on the technology and material.
4、 AR Coating
The coating divides into different colors, such as green, blue, purple, red.
The important keys are fastness, color difference, reflectance. A goods lens shows excellent in all keys.
5、 Super hydrophobic
It is extra waterproof layer on normal AR coating. It’s called SHMC, HMCS, HMC+, HMC PLUS as well.
