N-BK7 Plano-Concave Spherical Lenses Uncoated or AR Coated
Product description
Plano-concave lenses diverge a collimated beam from a virtual focus and are commonly used in Galilean-type beam expanders. Given their negative focal length and negative spherical aberration, plano-concave lenses can be used to balance out aberrations of other lenses in the system.
- Negative Focal Length Used to Diverge Collimated Beams
