Athermalized LWIR Lens 7mm F/1.0 Description
Athermalized LWIR Lens 7mm F/1.0 is a high-performance optical lens designed for long-wave infrared (LWIR) imaging systems, offering superior thermal stability and consistent imaging quality across a wide range of environmental temperatures. Its athermalized design ensures that focus and clarity remain unaffected by temperature fluctuations, making it ideal for applications in harsh and variable conditions. The 7mm focal length provides a balanced field of view, offering both a wide coverage area and excellent detail, while the F/1.0 aperture allows for enhanced sensitivity to low-light infrared radiation, delivering sharp and clear thermal images even in low-visibility situations. This lens is commonly used in thermal cameras, security surveillance, industrial inspections, firefighting equipment, and military applications, where reliable, high-quality infrared imaging is essential. Its durable construction and advanced design make it suitable for critical, mission-focused use in a variety of industries.
