A biconvex lens, also known as a diverging lens or negative lens, has two inward concave spherical surfaces. Due to its structural characteristics, the focal length of the biconvex lens is negative, which means that when parallel light passes through the biconvex lens, the light will diverge outward on both sides of the lens. Its materials include K9 glass, fused silica, zinc selenide, zinc sulfide, germanium, silicon, lithium fluoride, magnesium fluoride, calcium fluoride and barium fluoride. So is a biconvex lens focused or scattered?
Double concave lenses are astigmatic. The two sides of a biconvex lens are concave, and the middle part is thinner than the edge part. This structure allows light to refract and diverge outward when passing through the lens, rather than converging.
The above is an answer to whether the biconvex lens is focused or scattered. We hope it is helpful to you. If you have any questions, please feel free to consult or leave a message online.
