# Plano concave lenses

Plano concave lenses have negative focal lengths with twice the radius of curvature. They produce virtual images, which can be seen through the lens. They diverge a collimated beam and vice versa. As with plano convex lenses spherical aberration is lowest, when the concave surface faces a collimated beam.
