Plano-Convex Lenses with one convex surface and one plane has a positive focal length.
To reduce spherical aberration, when a Plano-Convex Lens is used for collimating and focusing a beam of light, the beam should be incident on the surface of the lens; When used for point light source collimation, the beam is incident on a plane.
It is commonly used for applications such as reducing beam size, reducing focal length, or enlarging images.
