Lens
- A lens is an optical component whos surface curvature and refractive index are designed such that the direction of light incident upon it is controlled.
- Formulae exist for thin lens approximations to determine focal lengths etc.
- For an object at distance d whos image is formed at d'
- Formulae exist for thin lens approximations to determine focal lengths etc.
Bending
The ratio of the curvatures of a lens’s two refracting surfaces.
