Plano Convex Spherical Lens, Dia 50.8mm, Focal Length 250mm

Plano-convex lens are used to focus a collimated beam, produces a sharper focal spot when used with the convex side towards the beam source.

Plano-convex lenses are positive focal length elements that have one spherical surface and one flat surface. These lenses are designed for infinite conjugate (parallel light) use or simple imaging in non-critical applications. These optic lenses are ideal for all-purpose focusing elements.
