Optics Tutorial - 2 - Lens and focusing basics
Introduction to focusing light: 1) Spherical surface refraction 2) Anatomy of a lens (and a mirror) 3) Focal length 4) Sign of the focal length 5) Computing a "thin lens" focal length 6) Lens bending (introduction for later describing aberration balancing) Homework can be found at: http://www.opticsrealm.com/tutorials-and-videos/geometric ...
