What are LWIR Lenses?

LWIR lenses are specialized optics designed to capture thermal radiation emitted from objects. These lenses are engineered to operate effectively in the long-wave infrared spectrum, which typically ranges from 8 to 14 micrometers. The performance of these lenses plays a crucial role in the clarity and accuracy of thermal images, particularly in cooled camera systems.

Benefits of Cooled Cameras

Cooled cameras take thermal imaging to the next level by reducing sensor noise and improving image quality. They operate at lower temperatures, allowing for enhanced sensitivity and better resolution. By integrating an LWIR lens for cooled camera systems, users can achieve sharper images, enabling more accurate analysis.
