Why Use Plano Convex Lens?

Plano-Convex lenses are the best choice for focusing parallel rays of light to a single point. They can be used to focus, collect and collimate light. The asymmetry of these lenses minimizes spherical aberration in situations where the object and image are located at unequal distances from the lens.

What are plano concave lenses used for?

The plano-concave lenses are used to expand light beams or to increase focal lengths in optical systems. The Biconcave Lenses are often used to expand light beams or to increase focal lengths in optical systems, and are normally used in combination with other lenses.

How does a plano convex lens work?

More specifically, the two surfaces of a plano-convex lense function together by focusing parallel light rays to a positive focal point. ... The curved surface of a plano-convex lens has a focusing effect on light-rays, while the plane surface does not have a focusing or de-focusing effect.
