a type of lens that causes incident rays (parallel) to diverge after leaving the lens
A concave lens is a diverging lens. Concave lenses are thinner in the middle than at the edges. They can be used to diverge a beam of parallel light. Diverging Lenses
A lens that diverges (spreads out) parallel rays of light.
lens that refracts incident light away from the optical axis
lens which causes rays of light coming from the subject to bend away from the optical axis.
a lens that is thinner in the middle.
