Features of Infrared Lens:

Our range of Infrared Lens includes lenses with manual focus, fixed focus, and motorized LWIR lenses, with focal lengths ranging from 3.8 to 250. We provide multiple interface options, such as M34x0.5, M45x1, M34x0.5, M34x0.75, c-mount, and flange. The distance between the lens and the object being observed varies from 13.3 to 61.26.

Germanium is commonly used for LWIR lenses. Its exceptional durability, chemically inert properties, and high Knoop hardness make it an excellent choice for challenging environments. However, germanium lenses may experience significant defocusing due to thermal drift under specific conditions. In situations where temperature changes are expected, we suggest using our ZnSe LWIR lenses, which offer more stable focusing even with significant temperature variations.

Our LWIR zoom lenses provide sharp, high-resolution images throughout the entire zoom range, making them ideal for machine vision applications that require detailed imagery. We offer both discrete and continuous zoom lenses.
