Those look like what you sometimes can find in cdr drives.

As far as I've seen, those come in every type of CD drive (anything that plays CD/DVDs), even the old portable ones that you could jog with. They're also in some printer/scanners, some digital cameras, a few old webcams "Aiptek Pencam etc." and the larger ones "DLP" are in projection TVs or school projectors.
