What Is a Plano-convex Lens?
A plano-convex lens features one flat and one convex surface.
This lens design, with a greater curvature radius on the convex side compared to the flat side, focuses light rays. Optically, its focal length is equivalent to twice the radius of curvature of the convex surface. The images it forms appear behind the focal point, with their size dependent on the focal length and the distance from the incident light source.
A key advantage of plano-convex lenses is their ability to converge light, making them ideal for magnifying glasses, microscopes, and other optical applications. They are also relatively simple to produce, offering cost efficiency and widespread availability. However, they may exhibit chromatic aberration, leading to color fringing in images, and distortion aberration, which can cause image distortion.
