Plano-convex lenses are used to collimate diverging light or to focus collimated light. We use them as secondary focusing lenses to refocus the collimated light sources.
Plano-convex lenses have low spherical aberration. Use them with the plano side facing the point source or the focus and the curve side towards the collimated beam.

In a Lens, the following parameter are usually used to declare it: diameter(Φ),central thickness(tc),radius(R),edge thickness(te),focal length(f),reflective index. These parameters follow the following formulas:
