I have a selection of lenses taken from various scanners, some are from Canon flatbed scanners, a couple from high quality slide scanners and a couple of microfiche viewer lenses. They're all quite small, the flatbed lenses are all around 2cm long or shorter and about 2 cm in diameter. These work great as macro lenses for mobile phones and produce incredibly sharp results, especially those from 4800 dpi scanners. My mobile is just a Huawei P-Smart, not especially high quality but I get ok results. My favourite one is from a Canon 4400F flatbed scanner, it's got the widest field of view and has a decent depth of field. On the mobile phone I just attach them with a lump of blu-tac. There's a lot of mobile phone macro lens clips that could easily be adapted but blu-tac works fine for me as i don't like anything to be permanent due to the amount of experimenting that I do. All of these lenses can also be used on a dslr but on that type of set up the depth of field is very shallow and ideally you'd want to be focus stacking. On their own most of these lenses are all around f2 or thereabouts. On my dslr I mount these into adaptors that I then set into macro tubes. I'll post a few images here but there's a lot more on my flickr album at flic.kr/s/aHsmWnDvJ7
Stripping down lenses or things that contain lenses is a bit of a hobby of mine, in the past I used to build high quality teleconverters with glass scavenged from old zoom lenses and I'd use these in combination with my dslr mounted to a 600mm Skywatcher 80ED refractor telescope. Basically gives you a very high quality 600mm to 2400mm lens, albeit manual focus. Anyone interested in seeing those photos can see them here www.birdforum.net/gallery/users/paul-corfield.19132/
All of these scanner lenses focus from around 2" or less distance so you need a bit of stealth and a willing sitter but I find most critters are ok as long as you move slowly.
