Double Concave Lens:
The double concave lens is thin in the middle and thick at the
edges, consisting of twoconcave surfaces of equal curvature, with a
negative focal length, for diverging parallelbeams. Commonly used
for beam expansion of lenses, projection and expansion of thefocal
length of optical systems
