Tiny Aspheric Lens 1.45mm FL - What purpose would this lens have?

Found this lens on ebay, it has such a small diameter and focal length it caught my curiosity, anyone have any ideas on what this lens might have been created for?

-Numerical Aperture: 0.58

Smaller beam

That it will do, I'm wondering what use such a tiny small beam might have, I suppose the applications could be numerous but with such a small lens, I'm guessing its power handling capability would be fairly small.
