    摘要： Disclosed is a urethane (meth)acrylate oligomer which is obtained by reacting at least one polyoxyalkylene polyol (A), at least one monool (B1) soluble in the component (A) and/or at least one silane coupling agent (B2) reactive with an isocyanate group, at least one polyisocyanate (C) and at least one hydroxylated mono(meth)acrylate compound (D) at a ratio at which the equivalent weights of hydroxy groups, active hydrogen groups and isocyanate groups in the respective components satisfy the following formulae (1)-(3). The urethane (meth)acrylate oligomer does not substantially contain an unreacted isocyanate group. B(active hydrogen)+D(OH)=C(NCO)−A(OH) (1) 1.05≦C(NCO)/A(OH)≦2 (2) {C(NCO)−2A(OH)+2 m}×0.35≦D(OH)≦{C(NCO)−2A(OH)+2 m}×0.70 (3) In the formulae (1)-(3), A(OH) represents the total equivalent weight of hydroxy groups contained in the component (A); B(active hydrogen) represents the total equivalent weight of active hydrogen groups contained in the component (B1) and/or the component (B2); C(NCO) represents the total equivalent weight of isocyanate groups contained in the component (C); D(OH) represents the total equivalent weight of hydroxy groups contained in the component (D); and m represents the number of moles of the component (A).

    摘要： A method and apparatus for measuring a refracting power of an optical system to be inspected. A beam source generates a luminous flux which passes through the optical system to be inspected. A rotating plate intermittently blocks the beam after passing through the optical system to be inspected. A beam receiving element receives the beam passing through the optical system to be inspected and intermittently blocked by the rotating plate, and outputs a beam reception signal based on the received beam. A rotational position detector detects a rotational position of the rotating plate and outputs a rotational plate detection signal based on the detected rotational position of the rotating plate. Further, a calculating means calculates the refracting power of the optical system to be inspected based on a change quantity from the detected rotational plate detection signal to the detected beam reception signal.
