1. Reflectivity of Camera Phone Lens : Effect of ARC |
[TOP] |
|
|
| |
 |
| |
|
| |
Reflectivities of camera phone lens are compared. The reflection spectra of lenses before they are anti-reflection coated(upper middle), and after they are anti-reflection coated(upper right) are shown.
Thickness of ARC film is 58.4 nm. Reflectivity decreases from ~10 % to 2~4 % after AR coating. Backside reflection from the opposite side of lens is included. |
