Focal Length Of Combination Of Lenses Formula at Carolyn Bevers blog

Focal Length Of Combination Of Lenses Formula. i have found the formula for the effective focal length $f$ of two thin lenses with focal lengths $f_1$ and $f_2$ separated by distance $d$ to be if a lens is biconcave, a beam of light passing through the lens is diverged (spread); the two lenses thus function together as a single lens, with a combined focal length. This equation (4) also called the combination of lenses formula. therefore focal length of the combination of two lenses in contact is given by. the distance from the second lens to the focal point of the combined lenses is called the back focal length (bfl). The focal length of a thick lens. this means that the combination of lenses is replaced by a single lens having a focal length f and it forms the image at i when the object is placed at s. the combined focal length for two thin lenses separated by a distance a (figure 2) is given by the equation: Note that this equation is only valid if the lenses. As d tends to zero, the value of the bfl tends to the value of f. The lens is thus called a negative or diverging lens.
