In the LWIR, or long-wave infrared, systems are typically uncooled and therefore have less sensitivity. However, long-wave infrared lenses allow the user to see through dust or smoke, which makes them particularly valuable in certain environments and applications. They are also less expensive than some other infrared lenses. The lower price point allows many units to be purchased, when it is necessary to provide the benefits of infrared vision in day and night to many people or military troops.
