Miniature high-definition fisheye lens

The invention relates to the technical field of optical imaging, in particular to a miniature fisheye lens with the full working view field range of 160 degrees, the receiving aperture is F/5, and the miniature fisheye lens is particularly suitable for high-definition shooting. The system has the characteristics of high imaging performance and resolution, simple and compact structure, and easy processing and installation. According to the utility model, 1, a first lens with a negative meniscus shape, a second lens with a negative meniscus shape, a third lens with positive focal power, a fourth lens parallel to a flat plate, a fifth lens with positive focal power and a sixth lens with negative focal power are sequentially arranged from an object space to an image space along the optical axis direction; the first lens and the second lens are both negative meniscus lenses, and the optical surfaces, facing the object side and the image side, of the first lens and the second lens protrude towards the object side.
