Lenses are used to focus light and form images. There are a variety of possible types; we will consider only the symmetric ones, the double concave and the double convex.. Q1: A double convex lens has radii of 5 cm and 20 cm a thickness of 2 cm and an index of 3/2. . Locate both H principal and focal points and compute the image distance for an object 16.4 cm in front of V1. 23.7 Thin Lenses; Ray Tracing. Parallel rays are brought to a focus by a converging lens (one that is thicker in the center than it is at the edge).. Double convex . lens. 23.7 Thin Lenses; Ray Tracing. Michael Fowler, . UVa.

Rays close to the axis (“paraxial”) will focus to an image inside the glass:. Let’s us predict mathematically the properties of an image produced by a lens. Defining Variables. f = focal length, distance from the focus to the optical centre (F and F’ are the same distance from O)..
