description The invention relates to the technical field of optical lenses, in particular to an uncooled long-wave infrared wide-angle lens and an aircraft. The uncooled long-wave infrared wide-angle lens comprises a first lens, a second lens, a diaphragm gear, a third lens and a fourth lens which are sequentially arranged from the object side to the image side of an optical axis. The first lens is a meniscus lens with negative focal power, the object side and the image side of the first lens are respectively a convex surface and a concave surface, the second lens has positive focal power, the object side and the image side of the second lens are both convex surfaces, and the diaphragm gear is located on the second image side surface of the second lens. The third lens is a meniscus lens with negative focal power, the third lens is a concave surface and a convex surface on the object side and the image side respectively, the fourth lens has positive focal power, and the fourth lens is convex surfaces on the object side an
