Abstract
A method of forming a chalcogenide glass element, the method includes depositing molten chalcogenide glass from an injection tip of a nozzle and into a cavity of a mold at a flow rate, the nozzle being inserted into the cavity, and during the depositing, moving at least one of the nozzle and the cavity relative to each other to substantially fill the cavity with the molten chalcogenide glass, and changing the speed of the at least one of the nozzle and the cavity based upon alignment of the injection tip with a cross-sectional radius of the cavity.
