WebThis image is at the focal point of the lens, s 2 = –f 1, because a well-collimated laser yields s 1 ~ ∞, so from the Gaussian lens equation s 2 = f. Adding a second lens with a positive focal length f 2 and separating the two lenses by the sum of the two focal lengths –f 1 +f 2, results in a beam with a radius y 3 = θ 2f 2 and ...
