Should be fun.

1. Simple ARCs work because of the 1/4 wavelength rule. But that is a single wavelength at a specific angle. How are multiple wavelengths dealt with? More importantly, how are coatings that deal with blue light created (where a narrow band of wavelengths are more sharply interfered with).

2. How do oleophobic and hydrophobic coatings work? Is it another layer of some kind of material?

3. What the heck is destructive interference really? How does one light ray know that another is moving opposite of it? Does it not work if they are a certain distance from each other?

4. Do the oleophobic and hydrophobic coatings break down over time?

5. How does ARC really allow higher light transmittance? I get that there's less reflection, and that's aesthetically better. But how does adding a layers on top of something allow MORE light to move through?

6. Is ARC on the back and front of lenses the same?

7. How did ARC begin? Did it start off as an opthalmic application?

8. Is something special done to lenses to insure that ARC adheres when the laser hits the puck? Does the inside of the chamber take on AR qualities as will?

9. Has AR always been applied the way it is today?


Phew! that's intense!
