Abstract: A method of fabricating a shaped optical element for refracting infrared light. The method can include providing a chalcogenide glass mass within a precision mold, the chalcogenide glass mass having a starting volume that is equal to or less than about 105% of the volume of the shaped optical element, precision molding the chalcogenide glass mass by providing heat and pressure to form the chalcogenide glass mass into a near-net shaped optical element, removing the near-net shaped optical element from the precision mold, and refining the near-net shaped optical element to generate the shaped optical element, the outside diameter of the near-net shaped optical element being less than or equal to 25 ?m larger than an outside diameter of the shaped optical element. The near-net shaped optical element can have an outside diameter less than 20 ?m greater than the outside diameter of the shaped optical element.
