Physical Principles & Mathematical Derivation
Biconcave lenses possess negative optical power (diopters < 0), spreading incident rays outward as if originating from the near-side focal point F. Used in eyeglasses to correct nearsightedness (myopia), they always produce 0 < M < 1 upright virtual images.
Questions & Concepts
What physical equation governs Diverging (Concave) Lens Ray Diagram Simulator (Myopia Optics)?
f < 0 ⇒ dᵢ = −(|f| × dₒ) / (dₒ + |f|), 0 < M < 1 — Biconcave lenses possess negative optical power (diopters < 0), spreading incident rays outward as if originating from the near-side focal point F. Used in eyeglasses to correct nearsightedness (myopia), they always produce 0 < M < 1 upright virtual images.
How are the equations of motion integrated in this simulation?
Nonlinear differential equations are integrated at 240–300 Hz substeps using classical 4th-order Runge-Kutta (RK4) to maintain strict Hamiltonian energy accuracy.
