Lense maker formula. The lensmakers equation relates the focal length of a simple lens with the spherical curvature of its two faces. Ray Optics and Optical InstrumentsTo. The derivation of lens maker formula is provided here so that aspirants can understand the concept more effectively.
For different optical instruments lenses having different focal lengths are used. Lens makers 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. In this session Tushar sir will be discussing the topic Lens Maker Equations Mirror Formula with practice multiple choice questions from Class 10 Physic.
It is used by lens manufacturers to make the lenses of particular power from the glass of a given refractive index. We will discuss the form of the equation that is applicable only to thin lenses. The radii of curvature here are measured according to the Cartesian sign convention.
Lens manufacturers commonly use the lens maker formula for manufacturing lenses of the desired focal length. This is so-called as the formula helps lens manufacturers in finding the radii of curvature of the required lens. The focal length of the lens is dependent on the radii of curvature and the refractive index of the lens.
Where and represent the radii of curvature of the lens surfaces closest to the light source on the left and the object on the right. The focal length of a lens depends on the refractive index of the lens and the radii of curvature. The Lens Makers Formula Lens manufacturers use the lens makers formula to manufacture lenses of the desired focal length.

A lens is a transmissive optical device that focuses or disperses a light beam by means of refractionA simple lens consists of a single piece of transparent material while a compound lens consists of several simple lenses elements usually arranged along a common axisLenses are made from materials such as glass or plastic and are ground and polished or molded to a desired shape. Lenses of different focal lengths are used for different optical instruments.
