PHY2061 R. D. Field Department of Physics chp40_8.doc University of Florida Two-Lens Systems Consider two lenses separated by a distance L . Step 1 : Let p 1 be the distance of the object from lens 1. Find the location of the image, i 1 , from lens 1 ( ignoring lens 2 ) using 1 1 1 1 1 1 f i p = + and m 1 = -i 1 /p 1 . Step 2: Take the image formed in step 1 as the object for lens 2 . Take p 2 positive if image 1 is to the left of lens 2 ( regardless of whether image 1 is real or virtual ) and take
