The biconcave lenses are used in optical systems in combination with other lenses. These lenses also work as beam expanders, optical character readers, viewers and projection systems.

  • Lower spherical aberrations than for Plano-Concave lenses
  • Diverges incident light
  • Ideal for Experimenting and Prototyping Applications
