Ultra-Wide Aperture and Athermalized LWIR Lens Design

In long-wave infrared (LWIR, 8–12 μm) optical systems, achieving a balance among large aperture, compact form factor, thermal stability, and high imaging performance remains a fundamental design challenge. These requirements are often mutually constraining, particularly in applications demanding long-range detection, wide field coverage, and reliable operation across extreme environmental conditions. Conventional design approaches frequently encounter limitations in simultaneously optimizing aberration correction, athermalization, and manufacturability.
