Transcribed Image Text:16 Find the system matrix for a Cooke triplet camera lens.
Light entering from the left encounters six spherical
surfaces whose radii of curvature are, in turn, r to r6. The
thickness of the three lenses are, in turn, t to 13, and the
refractive indices are n to n3. The first and second air
separations between lens surfaces are d, and d2. Sketch the
lens system with its cardinal points. How far behind the last
surface must the film plane occur to focus paraxial rays?
Data: r = 19.4 mm
t = 4.29 mm
n1 = 1.6110
n2 = 1.5744
n3 = 1.6110
r2 = -128.3 mm
t2 = 0.93 mm
r3 = -57.8 mm
13 = 3.03 mm
rA = 18.9 mm
di = 1.63 mm
d, = 12.90 mm
rs = 311.3 mm
r6 = -66.4 mm
