- 1 + So 1 Thin Lens Equation: Mr = Si Yo So Principle Ray: the ray from object to lens that is parallel to the principle (optical) axis will refract in a path that intersects the image focal point. Focal Ray: the ray from the object whose path is directed towards the object focal point will refract in a path parallel the principle (optical) axis. Central Ray: the ray from the object whose path is directed towards the center of the lens (intersection with the principle axis) will emerge from the lens undeflected.
