Imaging by Two Thin Lenses 1 Two thin lenses are in air as shown in the fgure. For the frst lens, the le±thand sur±ace is convex and the magnitude o± the radius o± curvature is 25 mm . For this frst lens, the righthand sur±ace is planar (normal to the axis o± the optical system). For the second lens, the le±thand sur±ace is concave and the magnitude o± the radius o± curvature is 25 mm . For this second lens the righthand sur±ace is planar (normal to the axis o± the optical system). The re±ractive indices o± both lenses are 1 . 500. The lenses are spaced 50 mm apart. A real point object exists 150 mm to the le±t o± the frst lens. Light is propagating ±orm le±t to right. The point object is 50 mm above the axis o± the optical system. Cal- culate, showing all work and using the paraxial ray approximation, the location o± the fnal image along the optical axis to the le±t or to the right o± the second lens. The im- age o± the frst lens acts as the object ±or the second lens. Calculate, showing all work,
