half Ball Lens


He Rui optics' half-ball lens is a specialized form of a spherical lens, consisting of a hemisphere. These lenses are made from high-quality transparent optical glass materials and feature a precisely convex surface on one side, with the other side being flat. This unique configuration allows light to be focused or diverged depending on the direction of the lens.

The working principle of the half-ball lens is mainly due to its curvature and symmetry. When light passes through the convex surface, it undergoes refraction, which is the bending of light as it transitions from one medium to another. This bending of light makes the half-ball lens useful in applications ranging from focusing light to diverging or converging light in a specific area. This versatility makes half-ball lenses valuable across various industries, from scientific research to telecommunications.
