Product Description
Professional manufacturer magnifying glass double convex lens for optical system
Convex lenses are thicker at the middle. Rays of light that pass through the lens are brought closer together (they converge). A convex lens is a converging lens.
The distance between the principal focus and the centre of the lens is called the focal length.
We JLGD could offer various kinds of optical lens such as convex lens, concave lens, flat-convex lens, etc. With our strong working team, we could process special lens according to the customer drawings. Welcome to visit our factory and hope to build a long and stable relationship with you customers.
\t\t\t\t\t\t\t\t\tSpecification \t\t\t\t\t\t\t
Biconvex lens means that both sides of the lens are convex, and their curvature is usually equal. It is mainly used to gather light from point source or transfer image to other optical systems. Because the object distance and image distance are equal or nearly equal, the distortion can be minimized.
