2 : Thin Lens Approximation

For thin lenses (lenses with small thickness compared to their focal length), you can use the thin lens approximation: $(\frac{1}{f} \approx (μ - 1) (\frac{1}{R_{1}} - \frac{1}{R_{2}})),$ where μ is the refractive index and R₁ and R₂ are the radii of curvature of the lens surfaces.
This simplifies calculations for thin lenses without needing the lens maker’s formula.
