# Lensmaker Equation Calculator

Lensmaker Equation is used to determine whether a lens will behave as a converging or
diverging lens based on the curvature of its faces and the relative indices of the lens material
and the surrounding medium. It is used for determining the focal length of a thin lens
(thickness = 0) with radii of curvature r1 and r2.
The focal length of a lens in air can be calculated from the lensmaker's equation.

#### Lensmaker's equation:

1/f = (n_{1}/n_{m}-1) * (1/r_{1}-1/r_{2})
**Where,**
**n**_{1} -Refractive Index of Lens Material
**n**_{m} -Refractive Index of Ambient Medium
**r**_{1} -Radius of Curvature of the First Surface
**r**_{2} - Radius of Curvature of the Second Surface
Basically, the Lensmaker Equation is used to make Lenses.
This online calculator helps you dynamically to determine the focal length of the lens.
