Consider a convex lens with an optical center O.
Derive lens maker formula for double convex lens. 1v- 1u 1f. This is done to make ray optics calculations simpler but the first step would be to identify what constitutes thin and thick lenses. Let R 1 R 2 are the of curvature of the surfaces ABC ADC of the respectively.
The double refraction can be ignored if the lenses in optics are thin enough to make the assumption that light is refracted only once. Lens Maker Formula Derivation.
