These LWIR lenses are used in a variety of markets including
defense, industrial, commercial and automotive applications. Bruce Bernacki, LightPath Chief Technology Officer, said, "The Black
Diamond (TM) LWIR aspheres are manufactured using our precision molding
technology, similar to the technology that is used to make our existing line
of visible and NIR aspheres. Black Diamond(TM) LWIR
moldable glass has several advantages over Germanium, which is traditionally
used for aspheric LWIR optics . Black Diamond(TM) aspheric lenses can be
used in environments up to 300 degrees C, enabling a range of applications
that were not previously possible with Germanium. Eastern Time on Tuesday, August 9, 2005, can access the event at
