Clever explanation of AR coating...

[Brice]

Hi.
I've found out this applet, giving to me perfect explanation of the AR coating :
(one of the most astounding Breitling achievements |>)

You can handle cursors on left ; by varying coating thickness and indexes of refraction, you can annihilate glare :
the upper wave (in blue) summed to the under wave (in red) must produce a flatten reflection wave (in black)...

Cheers,

Hello Brice!
Thanks for the link; I didn't know that a good AR coating was that difficult to achieve. In many cases the black line cannot be fully zeroed out.
And this is just for flat crystals!

Have a great day,
Don

Hi Don.
Yes indeed, AR coating seems to be quite a tough task ! :think:

BTW, please, send us some other pics of your US tour... :-p ;-)

Cheers, my friend,
Brice
