Collimating light from flat sources

I first hanged this question in the LED forum but maybe
here it is more appropriate:

If one has flat LED emitter of diameter x mm, how to collect and collimate light from it in a beam of y mm diameter?

For example, if one has circular LED emitter with active area of 9 mm how to collimate light from it into a beam of 9 mm? Or if the emitter has 17 mm how to collimate it into 9 mm?. Where one could buy optics for such collimators?
