title = "Microlenses fabrication on glass by combining laser with thermal-reflow technique",
abstract = "We describe a hybrid technique for fabricating microlens arrays on soda-lime glass substrates composed by a direct-laser write and post thermal treatment. In particular we use a nanosecond Q-Switch Nd: YVO4 laser and a mufla Heraeus furnace. Temperature dependence of the reflowing process was analyzed in the range of 620°C-670°C. An improvement in the optical quality of the microlens arrays were obtained as temperature increases. The best microlens array was obtained at 670°C with the following characteristics: diameter 47.89±6.65μm; focal length 510±10μm; and focal spot size 2.82±0.02μm. The presented technique has been shown to be capable of fabricating low cost microlens arrays with good optical quality.",
