Overview: Plano-concave (PCV) lens has one flat and one inward
curved surface. PCV lenses have a negative focal
length, diverging a collimated beam from a virtual focus
and are commonly used for image reduction or to spread
light. Star Optic provides plano-concave lenses fabricated
from N-BK7, N-SF11, UV-fused silica, calcium fluoride, zinc
selenide and etc. General Specifications Of N-BK7 Plano Concave (PCV) Spherical
