Optir™ utilizes the benefits of moldable infrared chalcogenide glasses and the expertise of Rochester Precision Optics molding technology. Due to the rapid growth of the infrared industry, and because of the near universal use of germanium in IR optical systems, the utilization of germanium has greatly increased. The resulting demand has caused the price of germanium to escalate rapidly and considerable concern exists regarding its future availability and cost. Molding allows volume manufacturing without the high cost of capital and skilled labor involved in diamond turning Germanium aspheres.  Optir™ offers excellent part to part uniformity, lower manufacturing and material costs. The glass offers a low thermal change in refractive index (72 X 1O -6/ºC) which is a benefit to systems designers in avoiding thermal defocusing.
