Lwir Lens Application:

LWIR Lenses or Long-Wave Infrared Lenses are infrared lenses optimized for use from 8000 – 12000nm, the long wave infrared wavelength range. At Rising Optics we manufacture high performance LWIR lenses for applications ranging from medical to industry to security and defense.


Since LWIR lenses transmit light that is invisible to the naked eye, LWIR cameras have a wide range of important applications.  Our lenses are used in thermal imaging systems to provide quality control in factories, to enable predictive maintenance in industrial settings, and to enable clear surveillance imaging in spite of smoke or fog.  They can be used for gas leak detection, allowing potentially dangerous situations to be evaded before they become problematic.  In medical applications, an LWIR lens and thermal imaging provides a non-invasive, reliable way to detect temperature change on a cellular level, enabling medical professionals to detect abnormalities and assess a wide variety of conditions, including breast cancer, brain tumor, diabetes, and burn trauma.
