2. A telescopic lens consists of a convergent lens of 5 cm focal length and 5 cm in diameter placed 4 cm in front a divergent lens of focal length -8 cm and diameter 4cm. In addition, a stop ween the lens 2 em from the convergent lens with a diameter of 3 cm. Determine the aperture stop, the limiting entrance and exit pupils for an object 35 em away from the convergent lens. Find positions and diameters. system. b)...
(optical engr) An optical imaging system includes two thin lenses. The first lens has focal lengths f1 = 5 cm and f2 = 10 cm. The distance between the 2 lenses is 5 cm. An object with height h = 2.5 cm is placed 15 cm before (to the left of) the first lens. A. Use the lens equations to compute final image location and image size of the object in this two lens optical imaging system B. Plot an...

The compound microscope consists of two converging lenses: the objective and the eyepiece. Suppose the focal length f_1 of the objective is 20 cm, and the focal length f2 of the eyepiece is 20 cm. The separation between the objective and eyepiece is 66 cm. The object is located 30 cm in front of the objective. (These numbers are not realistic for a real microscope.) a. Calculate the location and magnification of the image, and state whether it is a...
Two lenses, one converging with focal length 20.0 cm and one diverging with focal length -10.0 cm are placed 20 cm apart. An object is placed 60 cm in front of converging lens. Determine (a) the position and (b) the magnification of the final image formed (c) sketch a ray diagram for this system.
Problem 1: Ray tracing with a converging lens A 17 cm high object is located 50 cm away from a converging lens with a focal length of 30 cm. The drawing below is to scale (but is not necessarily at a scale of 1:1). A. Draw a ray diagram to find the image, including the height and orientation of the image: you only need to draw 2 of the special rays, but you can draw more if you'd like. Use...
2 Find the final image and total magnification by accurate ray tracing and by calculation. A diverging lens Llwith focal point F1 is to the left of a converging lens L2 of focal point F2. An arrow to the left of L1 is being observed through the two lenses. a Draw an accurate ray diagram to find the image of the arrow formed by the two-lens system. Use a ruler. Be careful. Label your first image and the final (second)...
