We have developed a method of producing micro-lenses on soda-lime glass plates by combining the techniques of laser annealing and an ion-exchange method, henceforth referred to as the `laser ion-exchange method.' The use of this technique makes it possible to simultaneously increase the refractive index on both sides of a glass plate at the laser beam irradiation zone. The increase in the refractive index on both sides complement each other to make a high quality micro-lens with a very short focal length. This method can be applied for producing circular, noncircular, linear, and array micro-lenses.
