The invention belongs to the technical field of lenses, particularly to a high-definition super wide angle prime lens which comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens which are sequentially arranged from the object space to the image space, wherein the fourth lens and the fifth lens adopt plastic aspherical lenses; the first lens, the second lens, the third lens and the sixth lens are glass spherical lenses; the first lens is a convex-concave negative focal power lens; the second lens is a bi-concave negative focal power lens; the third lens is a bi-convex positive focal power lens; the fourth lens is a bi-convex positive focal power lens; the fifth lens is a bi-concave negative focal power lens; the sixth lens is a bi-convex positive focal power lens. According to the high-definition super wide angle prime lens, glass lenses and plastic lenses are reasonably combined, so that a large aperture is realized, the imaging quality is good, 4 megapixel can be realized under the precondition that infrared does not focus again, and clear and bright monitoring pictures can be realized even at night with a low illumination level; the lens has a temperature compensation function, and can be used at the temperature of minus 30 DEG C-80 DEG C without being out of focus.
