If I have an object and in front of it there's a diverging lens, and in front of that (furthest from the object) there's a converging lens can I just ignore the diverging lens when ray tracing for the image formed by the converging lens?
I figure if I were able to draw an infinite number of rays from the image of the object through the first lens (diverging lens) that at least three of the rays would pass through the three main points for the converging lens (through the centre of the lens, parallel to the optical axis, and through the near focal point). Is this correct? Does this allow me to ignore the first lens?
