Some people claim that the optical sensor can be cleaned,...i was not so sure of that and today i set out to prove or disapprove that claim.
I decided to cut one apart and see how it is put together.
I started with cutting through the brass insert and the aluminum on both sides and then carefully pried the two halves apart and peeled each layer back to expose what lies underneath.
There is actually 2 eyes on each side, one above the other. The eyes are tiny glass balls mounted on a chip board. the one side the brass cover plate has just a hole drilled through and the "eyes" are in plain view. However on this particular OS one of the eyes happens to be missing (so at least i did not sacrifice a potential good OS).
On the other side there is a very thin SS cover over the hole in the brass plate,That cover plate has 1 small slot on the top and a row of 7 smaller slots at the bottom, these 2 eyes are also mounted on a small chip board centered behind these top and bottom slots and they are not visible nor is there AFAIAC no possible way of cleaning the eyes on that side.
As you can see in the pics the slotted cover was also not with out damage as it is dented in and cracked, also it appears the encoder disc had been riding against it and wore a visible groove in it.
This OS came from one of my spare IP's and it is safe to say it was the cause of that IP's failure.:agreed:
Based on the above findings i will play myth buster here and say the myth is busted,... cleaning the eyes on a OS is not possible.:nonod:
