WebThin Lens Equation. A common Gaussian form of the lens equation is shown below. This is the form used in most introductory textbooks. A form using the Cartesian sign convention is often used in more advanced texts because of advantages with multiple-lens systems and more complex optical instruments. Either form can be used with positive or negative … WebThe focus of a diverging lens is on the same side of the lens as the impinging parallel rays. We will not need concave (diverging) lenses for our study of optics. The thin-lens equation relates the distance of the object from the lens, do, and the distance of the image from the lens, di, to the focal length of the lens, f. The thin lens ... hoover bulls
