The reciprocal of the focal length is called the refractive power that has units dioptre (inverse meter). Water droplets can be considered as convex lenses and the lens maker formula is applicable. If a convex lens, having focal length f, is cut along the principal axis, both the resulting pieces will have the same focal length f. The lens maker formula for a lens of thickness d and refractive index μ is given by, Depending on the shape of the lens, the radii change. The radii of these spheres are known as the radii of curvature of the lens. The curved surfaces of a lens belong to two spheres. The distance between the optical centre and the focus is known as the focal length. This point is known as the focus of the lens. When parallel light rays are incident on a lens, the refracted rays converge to a point (for a converging lens) or appear to diverge from a point (for a diverging lens). The sign convention should be followed in the application of the lens maker’s equation.įocal Length and Radius of Curvature Definition The formula applies to both types of lenses. The formula is used to construct lenses with desired focal lengths. Lens maker’s formula relates the focal length, radii of curvature of the curved surfaces, and the refractive index of the transparent material. The lenses can be classified as converging (convex) and diverging lenses (concave). It can have two curved surfaces or one curved and one plane surface. The lens is a refracting device consisting of a transparent material. So without any further ado, let’s begin by learning about Lens maker’s formula: In this article, we will understand about lens maker’s formula, lens maker equation, Focal Length and Radius of Curvature. The relation between the focal length of the lens, the refractive index of its material, and the radii of curvature of its two surfaces is known as the lens maker's formula. Therefore, we can conclude from this that the convex lens is not necessarily converging, and the concave lens is not necessarily diverging. The lens converges when the focal length is positive and diverges when the focal length is negative. If the gap between the two surfaces is very small, the lens is said to be very thin. It is possible to convert all equations in a document to the Professional or Linear formats, or a single equation only, if the math zone is selected or the cursor is in the equation.A lens is a transparent medium surrounded by two surfaces, at least one of which must be curved. The linear option will display the equation in either UnicodeMath format, or LaTeX format, which can be set in the Conversions chunk. The Linear option displays the equation as source text, which can be used to make changes to the equation if needed. The Professional option displays the equation in a professional format optimized for display. Just choose a structure to insert it and then replace the placeholders, the small dotted-line boxes, with your own values. The Structures group provides structures you can insert.
