In the use of pesticides, it is often encountered that the names of the pesticides are different and the active ingredients are not clear. To help the farmers clearly understand the drugs, some of the pesticide names commonly used in the production of pollution-free agricultural products will be introduced as follows (trade name-Chinese general) name):

Biconvex lenses are a simple lens comprising two convex spherical surfaces, generally with the same radius of curvature. Being a kind of simple lens, the biconvex lens has a wide range of applications of it, but it is not limited to, control and focusing of laser beams, quality imaging and also the other kinds of optical instruments.
In a biconvex lens or a Plano-convex lens, a collimated or accurately parallel beam of light passes through the lens and converges at a spot or focus coming behind the lens. In such a case, this lens is known as a converging or positive lens. The distance coming from the lens up to the spot is called the focal length of the lens. Since there is a curvature on both sides of the lens, there will be around two focal points and also two centers. The line that is drawn through the middle of the biconvex lens is known as the principal axis.
Biconvex Lenses- Uses & Applications
These lenses have around a number of uses of which some of them are listed below-
- Biconvex lens are used as a magnifying or condensing lenses.
- They are also used as objectives or magnifiers
- These are utilized in many imaging systems such as the telescopes, monocular, microscopes, binoculars, cameras, projectors, etc.
- These are used in producing the virtual image in case of a human eye and a real image in case of the photographic films or an optical sensor
- These lenses are also used as a burning-glass.
- These are used in the applications of image relays and also in various kinds of industries
- Hence, a biconvex lens is one of the best lenses that can be used in a condition where a beam of light incident on lens is diverging in nature and also the beam that leaves the lenses converges symmetrically.
