# Lens Maker Formula Proof

Lens Maker Formula Proof. Then on applying the refraction formula at the second surface. and equating both the equations. we will get the lens maker formula. The formula is as follows:

A number of idealizations. simpliﬁcations and approximations are used to By using the lens maker’s formula you can determine the focal length of the specific lens if you know the parameters such as refractive index and radius of curvature. The lens maker formula is commonly used by lens manufacturers for manufacturing lenses of desired focal length.lens maker formula derivationassumptionsthe following assumptions are taken for the derivation of lens maker formula.let us consider the thin lens shown in the image above with 2 refracting surfaces having the radii of curvatures r1 and. youtube.com

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. For a double convex lens the radius r 1 is positive since it is measured youtube.com

As per optical physics. lens formula relates the distance of an object (u). the distance of an image (v). and the focal length (f) of the lens. The concave lens creates an erect and virtual image ii’ at a range of q from the optical center of the lens. as shown in the below diagram.

A lens maker formula may be defined as the formula which gives the relationship for calc. For a thin lens. the power is approximately the sum of the surface powers. youtube.com

Derive lens maker formula f 1 = (n − 1) (r 1 1 − r 2 1 ). The lens maker formula is utilized to create a lens with a defined focal length.

#### Derive Lens Maker Formula F 1 = (N − 1) (R 1 1 − R 2 1 ).

The equation is as follows. 1 f = [n1 n2 − 1] × [ r1 − r2 r1 × r2] 1 f = [ n 1 n 2 − 1] × [ r 1 − r 2 r 1 × r 2] where. n1 is the refractive index of.

Where. v = distance of image formed from the optical center of the lens.

#### For A Thin Lens. The Power Is Approximately The Sum Of The Surface Powers.

The concave lens creates an erect and virtual image ii’ at a range of q from the optical center of the lens. as shown in the below diagram. Lets consider a convex lens and o be the optical centre ; Another situation that has to be considered is the lens maker’s formula accounting for objects that are present in different media.

#### The Lensmaker’s Formula Relates The Index Of Refraction. The Radii Of Curvature Of The Two Surfaces Of The Lens. And The Focal Length Of The Lens.

From equations (iii) and (iv). we obtain. In this video i will make you understand the derivation of famous lens makers formula which is important for class 12 exams.the lens maker’s equation is a f. In optics. the relationship between the distance of an image (v). the distance of an object (u). and the focal length (f) of the lens is given by the formula known as lens formula.
