N-SF11 Concave Plano Spherical Lens Diverge Collimated Beam

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.
