Thanks to Masky for digging away so well! 
Oh and guys, scroll down all the way to the end to the part where he has pics of mice opened up. Look what he says about the Intellimouse 1.1a !
and interestingly, Razer Diamondback5, Diamondback Plasma LE6, Logitech MX518 Gaming-Grade Optical Mouse all have the same sensor in them
Wow thats a gr8 link Masky & Eddy.
And really wanted to know how the optical mouse works
Hey Thanx man…had no clue so much goes behind such a small thijng we take for granted now.
^^ indeed..
Optical mice are great. I have been telling my friends to buy one ever since they first came out on the market.
Nice link.
