In reply to Make a Cellphone Macro Lens From An Old DVD Player
Interesting. Does it have to be a DVD lens? I've got an old non-functioning discman from many moons ago I could salvage the lens out of...

@FooSchnickens: The lens on a DVD is much different. The thickness of the DVD transparent substrate medium is half that of a CD, thus the objective lens of the DVD is different to mitigate spherical abberation. Also, the recording track width and optical wavelength are different. The DVD lens can be made backwards compatible for CD, but not vice versa.
