Thermal Lens

The Thermal Lens Series is a uniquely engineered line of Zinc Sulfide thermal lenses for the OEM market available in 8.6mm, 13mm, 18.8mm and 35mm.  These rugged, weather tested lenses are ideal for cameras used in mission critical situations including perimeter surveillance, search & rescue, port and marine security, border patrol, electrical inspection and energy conservation.

The Thermal Lens Series feature a practical transparency between 8-12 μm wavelength (LWIR) and offer an optional DLC Coating - engineered and tested to withstand extreme environments such as rain, saltwater and extended exposure to UV light. In addition, the proprietary “Athermalized” design allows the lens to maintain consistent focus and resolution during dramatic temperature changes (-4° F~158°F).

For this series, Computar has developed an innovative production process called “Sintering” - mold forming without machining, greatly reducing the cost of mass production and enabling higher manufacturing efficiencies. The unique ZnS Thermal Series mold forming process allows faster time-to-market and lower costs throughout the entire manufacturing process.
