This optical glass lens demonstrates refraction of light. This bi-concave lens has a diameter of5.0 cm with a focal length of 10 cm. A concave lens has a thinner centre than the edges. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. The image formed is smaller than the original image. Concave lenses are less commonly used than convex lenses. They are used in glasses to correct vision, and also in torches to spread out the beam of light so it covers a much wider area. The lens is made of optically worked glass, with ground edges, highly polished.
