Solve Common Lens, Mirror, and Refraction Problems

Our Optics Calculator uses fundamental physics equations to determine optical properties. Choose from lens equations, magnification, Snell's Law, or critical angle calculations.

  • 1

    Lens/Mirror Equation

    Calculate focal length, object distance, or image distance using 1/f = 1/do + 1/di.

  • 2

    Magnification

    Find image magnification using M = hi/ho = -di/do.

  • 3

    Snell's Law

    Calculate refraction angles using n1 * sin(θ1) = n2 * sin(θ2).
