(a) Variation of the sagittal radius δRM(Y) = RM(Y) − RM0 along the tangential direction of a 200 mm-long diaboloidal mirror defined by the conjugate parameters given by equation (33). (b) The contribution to the variation in plot (a) of the polynomial terms in equation (36) of higher than the first order, δR2,3,…(Y). |
