A one-step direct-write technique for fabricating spherical microlenses on soda-lime glass substrates is described. Using a Q switched Nd:YVO4 laser combined with a galvanometer system, square and triangular microlens arrays were fabricated. The focal length of microlenses is measured using direct and nondirect methods. Values around 118 and 125 mu m were obtained for the microlens focal length of square and triangular arrays, respectively. A noncontact profilometer is used for determining the surface roughness of square and triangular arrays. Results are compared with that of glass substrate. (C) 2010 Optical Society of America
