Calculate the focal length of a thin lens with our free Lens Maker Equation Calculator. Easily determine lens properties using the refractive index and radii of curvature for accurate optical design.
Formula:
The Lens Maker's Equation calculates the focal length (f) of a thin lens:
1/f = (n - 1) * (1/R1 - 1/R2)
- f: Focal length
- n: Refractive index of lens material
- R1: Radius of curvature of the first surface (positive for convex, negative for concave)
- R2: Radius of curvature of the second surface (positive for convex, negative for concave)
