WebThe latter lens has its back vertex a distance x behind the first lens, thus the two back vertex focal lengths are related by fxV'=fV'-x. Taking the reciprocal of this equation we obtain FxV'=FV'/(1-xFV'). where FxV'=1/fxV' and FV'=1/fV' are the back vertex powers of the two lenses. For astigmatic lenses, this must be applied to each meridian ...
