Bi Convex lens has a positive focal length, and with two outward surfaces. The two surfaces are with same radius of curvature, thereby minimizing spherical aberration. Some biconvex lenses are with different radius of curvature for both surfaces. Bi convex lenses always used as magnifying and condensing lenses. We manufacture bi convex lenses with competitive prices and quality. We offer custom made service for the spherical lenses, cylindrical lenses, and optical windows.

How does bi convex lens work in optical system ?
Bi convex lenses made of transparent glasses. They are thicker at the center than the edge. We also call bi convex lens a converging lens, because they refract parallel light rays so that they meet. So they are widely used for eyeglass, telescopes, microscope and magnifying glasses. But how does a bi convex lens ?
Bi convex lens has focal points on both sides of the lens, but it's necessary to use points at twice the focal length to locate objects and image. Therefore, along the principal axis, there are points identified as F and 2F on both sides of the lens.

As with mirrors, we only need to trace two rays in order to locate the image for lenses. Both rays change direction while inside the lens, and their convergence point on the opposite side of the lens is the image location. As can be seen in the figure above, Ray 1 approaches the lens parallel to the principal axis and is refracted through the focal point on the other side. R2 travels through the focal point and is then refracted parallel to the principal axis. The yellow arrow on the right of the lens is inverted image.
