The derivation of lens maker formula is provided here so that aspirants can understand the concept more effectively. Lens manufacturers commonly use the lens maker formula for manufacturing lenses of the desired focal length.
Lens maker’s formula is the relation between the focal length of a lens to the refractive index of its material and the radii of curvature of its two surfaces. It is used by lens manufacturers to make the lenses of particular power from the glass of a given refractive index.
6 days ago · 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. In this article, we will understand about lens maker’s formula, lens maker equation, Focal Length and Radius of Curvature.
Lensmaker's Equation. 🔗. In Section 47.7 we stated that object distance p, p, image distance q q and focal length f f are related by. 1 p + 1 q = 1 f. 1 p + 1 q = 1 f. 🔗. Focal length is a property of the lens and the media around the lens, being positive for convex lens and negative for concave lens. 🔗.
The lens maker formula is utilized to create a lens with a defined focal length. Learn more about lens markers formula and solved example.
The lens maker’s formula involves the focal length, refractive index of the material of the lens and the radius of curvature of the two surfaces of the lens. This formula is derived from the refraction of light on the two spherical surfaces of a lens.
