WebOriginally, the concept was developed in geometrical optics for calculating the propagation of light rays with some transverse offset r and offset angle θ from a reference axis (Figure 1). As long as the angles involved are small enough (→ paraxial approximation), there is a linear relation between the r and θ coordinates before and after an optical element. WebWithout a lens, these rays could represent either an object at negative infinity or an image at positive ... Thin lenses, which also have zero thickness, may have aberrations. However, the term “thin lens” is commonly used to describe both of these idealized elements.
