Double Convex Spherical lens

A bi convex lens is a biconvex lens sheet that includes an incident surface and an emitting surface, characterized by a longer focal length at the middle of the lens face and a shorter focal length at the end of each lens face. The biconvex lens is mainly used to converge flight from a point source or to transmit images to other optical systems.

Spherical lens is the most basic optical component of the microscope optical system, the objective lens, eyepiece and focusing lens and other components are composed of single and multiple lenses. Depending on their shape, they can be divided into two categories: convex lenses (positive lenses) and concave lenses (negative lenses).

China Star Optics can provide different kinds of spherical lenses like plano concave lens, plano convex lens, achromatic lens. If you want to know more information about a plano-convex lens/mirror, such as the use and refractive index of a plano-convex lens, please contact us.
