What kinds of spherical lens can be divided into? What are the characteristics of each? Manufacturer of spherical lens introduce to you:
Spherical lens is a refractor whose refracting surface is a transparent body with two spheres or one sphere and one plane. Generally, it can be divided into two categories: convex lens and concave lens; The central part is thinner than the edge part, which is called concave lens. There are three kinds: double concave, flat concave and convex concave. Convex lens has the function of converging line, so it is also called "converging lens" and "positive lens" (it can be used for hyperopia and presbyopia)
Manufacturer of spherical lens This kind of lens can be divided into: A. biconvex lens, a lens whose two sides are ground into convex spheres; b. Planoconvex lens is a lens with one side convex and one side flat; c. Concave convex lens is a lens with one convex side and one concave side. Concave lens has the function of dispersing light, so it is also called "divergent lens" and "negative lens" (which can be used for myopia glasses). This kind of lens can be divided into: A. double concave lens is a lens with two sides; B. double concave lens is a lens with two sides; b. Plano concave lens is a lens with one side concave and one side flat; c. Convex concave lens - a convex and concave lens
