WebViewed 4k times. 1. I know the formula that when two lenses are separated by a distance d, then the resultant focal length is given by :-. 1 f = 1 f 1 + 1 f 2 − d f 1 ⋅ f 2. However , there are two doubts that arise in my mind. 1) My book says that a combination of two thin lenses can only be replaced with a thick lens. WebIn optics, a doublet is a type of lens made up of two simple lenses paired together. Such an arrangement allows more optical surfaces, thicknesses, and formulations, especially as the space between lenses may be considered an "element". With additional degrees of freedom, optical designers have more latitude to correct more optical aberrations ...
