WebWhen the third lens is removed, f1= f 11+ f 21, where f= 760 This means, 121 = 7601 + f 31 ⇒ f 3=−30 cm Since f 3 is negative, it is a diverging lens having focal length 30 cm. formula Combination of thin lenses in contact Consider two lenses A and B of focal length f 1 and f 2 placed in contact with each other. WebApr 7, 2024 · The lens maker formula for a lens of thickness d and refractive index μ is given by, 1 f = ( μ − 1) [ 1 R 1 − 1 R 2 + ( 1 − 1 μ) d R 1 R 2] Here, R1 and R2 are the radii of curvature of the two surfaces. For a thin lens, the thickness d is taken to be zero. The lens maker equation for a thin lens is given by, 1 f = ( μ − 1) ( 1 R 1 − 1 R 2)
