A diverging lens helps in throwing a parallel beam of light, which spreads throughout the area. A diverging glass is used in making of a laser/torch light , diverging lens or concave lens is exactly the opposite with the outer surfaces curving inward, so it makes parallel light waves curve outward or diverge and spread out into the distance means it produces a broader range of light.
