Abstract
An anamorphic lens, which includes a cylindrical lens and a spherical lens arranged in sequence from the object side to the image side. The first lens, the second lens, and the third lens are arranged in sequence from the object side to the image side, the first lens and the second lens are cylindrical lenses with negative refractive power, and the third lens has positive refractive power Cylindrical lens. Using the optical characteristics of the cylindrical lens, the incoming horizontal light is 'compressed', while the light entering the vertical field of view remains unchanged. After the comprehensive aberration correction of the light, the horizontal field of view angle is increased by 33%. Achieve 1.33× anamorphic shooting. At the same time, because the lens of this solution is smaller in size, lighter in weight, and relatively low in cost, it can better meet the needs of most ordinary users.
