Shortcut for thin lens equation
SpletA lens may be considered a thin lens if its thickness is much less than the radii of curvature of its surfaces ( d ≪ R1 and d ≪ R2 ). In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the radii of curvature of the lens surfaces. SpletThe formula is as follows: 1 v − 1 u = 1 f Lens Formula Derivation Consider a convex lens with an optical centre O. Let F be the principle focus and f be the focal length. An object AB is held perpendicular to the principal axis at a distance beyond the focal length of the lens.
