Description
Plano Concave Lens with AR Coating and K9 Optical Glass for Negative Focal Length Applications

Plano-concave lenses diverge parallel light outward. They have negative focal lengths and negative spherical aberrations, and can be used to correct phase and spherical aberrations.

Key Features
  • Diverges Parallel Light
  • Negative Focal Length
  • Corrects Phase
  • Corrects Spherical Aberrations
