Default Photos of Laser Damaged CCDs?

Hello All,

Does anyone have photos of their laser damaged ccds? I'm not looking for photos taken with a damaged sensor, but the actual damaged sensor itself. What I'm getting at is, do laser pointers leave any unique patterns on the ccd sensor itself when shined directly upon it? Etchings? Deep burns? Bubbles?


I'd appreciate any insight into this.

Even after focusing a 1 watt 445nm laser on an old webcam that I had (directly on the CCD), I could not notice any visual markings of it being damaged, although I'm pretty sure it's unusable now.

This is after focusing the laser on the CCD for about 10 seconds:


However, it does create a cool diffraction when you shine it onto the chip

I think you need to look at it under a microscope to see the damage...

Lol, no problem. Although I can't speak for how the ccds look in some of the webcams that were running when it happened, like this one:

Lotus, I saved a copy (now deleted from youtube iteslf) of photonicinduction's goodbye to youtube video's where he repetively tries to fry his CCD with his green laser.
(these two videos are now gone at youtube)

I saved it because I could barely hear it on youtube and intended to play it with VLC
where I can turn up the volume much higher.

It took several attempts, I was surprised, he did not kill his CCD but DID end up with one
with many spots that no longer worked.

@Cornbluth, photonicinduction did not show us what his CCD apeared like from the outside, sorry if I cannot answer you and may have taken this off topic a bit.
