BD6 Infrared Chalcogenide Glass

With a long history of experience in Chalcogenide Glass production, LightPath produces a variety of different Chalcogenide glasses in its Orlando, Florida facility.

All of LightPath’s Black Diamond™ Chalcogenide glasses are produced in boules of 120mm diameter, and can be further expanded using our proprietary molding technology, to larger diameters, as needed. Our Black Diamond™ materials are designed specifically to have the same refractive index whether polished by diamond turning into lenses, conventionally polished, or molded into final form using our precision glass molding technology.

We produce our BD6 glass in quantities of up to 10 metric tons annually, and can further expand our production capacity. Like many other manufacturing processes at LightPath, most of our critical production equipment for these processes is either designed and built by LightPath engineering team, or by modifying existing commercial equipment. This allows us to achieve unique properties, such as materials that have the same refractive index whether molded or polished by Diamond Turning.

In November of 2021 LightPath received from the US Naval Research Laboratories (NRL) an exclusive usage license for additional Chalcogenide glasses developed by NRL’s scientists. LightPath is currently in the process of transitioning these materials into production. For more details, please contact us.
