On the class of functions analytical and bounded in a half-plane with bounded derivative of order $n\ge0$, we solve problems of optimal recovery of values of a function and its derivatives of order $m\ge0$, using the restriction of the spectral function. We obtain appropriate exact inequalities for functions analytical in a half-plane.
