Optical Glass Plano-Concave Lenses

Plano-Concave Lenses have a negative focal length and is typically used to cause a collimated beam to diverge as in a Galilean type beam expander or Telescope.
1. Beam expansion
2. Light projection
3. Expanding an optical system’s focal length

Optical Glass Plano-Concave Lenses


1. Beam expansion
2. Light projection
3. Expanding an optical system’s focal length

Plano-Concave Lenses are with negative focal lengths and they can be used to diverge collimated beams; in this case, the curved surface should face the source in order to minimize spherical aberration. In addition, they can be employed to offset the effects of spherical aberration caused by other lenses in an optical system. Because the spherical aberration of the Plano-Concave is negative, it can be used to balance the aberration of other lenses.
