The total distance from the laser to the focused spot is …
WebCombination of thin lenses Consider two thin convex lenses L 1 and L 2 of focal length f 1 and f 2 placed coaxially in contact to each other. A point object O is placed in the principal axis at a distance u from the lens L 1.In the absence of lens L2, as the rays of light incident on the lens L 1, this lens L 1 converges the rays, and thus, image is formed at point I 1. WebA lens or mirror can be compared with a master as it is being ground, allowing it to be shaped to an accuracy of less than a wavelength over its entire surface. Figure 3.15 …
