Plano Concave Lens
| Plano Concave Lens has a
negative focal length and is typically used to cause a collimated
beam to diverge as in a Galilean type beam expander or Telescope.
Because the spherical aberration of the Plano-Concave is negative,
it can be used to balance the aberration of other lenses.This lens
is widely use in optical display systems, projection optics systems,
imaging and laser measureemnt systerms. |
