Concave convex lens

Concave convex lens

It is a thicker lens in the center. Convex lenses are divided into biconvex, plano-convex, and concave-convex (or positive meniscus) forms. The thin convex lens has a converging effect, so it is also called a condenser lens, while a thicker convex lens is expected to be far away, diverging or converging, which is related to the thickness of the lens.

Different effects on light

Convex lens mainly converges light

The concave lens mainly diverges the light

Two, imaging is different

The convex lens can enlarge the virtual image upright, enlarge the real image upside down, enlarge the real image upside down, and reduce the real image upside down;

The concave lens can only be upright to reduce the virtual image
