Bi-concave lenses
Bi-concave lenses, like the plano concave lenses diverge collimated light and vice versa. Because both concave surfaces contribute to light refraction bi-concave lenses can be made with shorter focal lengths than the plano concave type. They are often used with other lenses to decrease system focal length.
