Optir™ Optics
Infrared Glass Molded LWIR Aspheric Optics

• Wavelength 1-14µ
• Molding technology for lowest cost advantage
• Excellent part to part uniformity
• Low thermal index change avoids thermal defocus
• Excellent match with aluminum assemblies

Optir™ Optics combine 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 the near universal use of germanium in IR systems, the demand for germanium has greatly increased. This demand has resulted in higher prices and limited supply. Molding allows volume manufacturing without the high cost of capital equipment and skilled labor.   Optir™ glass offers excellent part to part uniformity, with lower manufacturing and material costs. The glass also offers a low thermal change in refractive index (72 X 1O -6/ºC) which is a benefit to systems designers in avoiding thermal defocusing.
