Abstract
A method for the use of light pressure to optically center a lens on a source of emitted light with submicron accuracy. In one aspect the method uses light pressure to optically center a lens on a source of emitted light, where the lens is then fixed in place. In another aspect the method uses light pressure to create an optically centered lens from a dielectric liquid on a source of emitted light, the shaped lens is then fixed to form an optically aligned permanent lens. By choosing the appropriate lens the light emitted from the source can be either focused or collimated.
