Double-Concave Lens Optical Lenses

• 

double-concave lenses have negative foccal lengths, diverge
collimated incident light and form only virtual image which
are seen through the lenses. They are often used to expand
light beam or increase focal lengths in existing systems
and are normally used in combination with other lenses.
In a single lens application you shoud consider using
them in prefenrence to a single plano-concave lens
if the magnification lies in the region.
