Refracting surfaces of spherical and rod microlenses have been made with the melting method. Size of spherical lenses ranged between tens of microns to hundreds of them. Length of rod lenses ranged between hundreds of microns to about some millimeters. Diameter of these last lenses ranged between hundreds of microns to about 1.2 mm. The testing of the refracting surfaces has been done by means of a Scanning Electron Microscope and an Atomic Force Microscope. An USAF test target has been used to find the resolution of the lenses. Theoretical behavior of the lenses has been obtained through ray tracing. Applications of the microlenses in combination with VCSELs and in other field are presented.
