摘要： A progressive power lens whose distance viewing vertex power is a negative value and in which a surface refractive power Pf.sub.m in the main meridional plane in a distance viewing portion is larger than a surface refractive power Pf.sub.s in a plane perpendicular to the main meridional plane (Pf.sub.m >Pf.sub.s). A surface refractive power Pn.sub.m in a section in the main meridional plane in a near viewing portion is smaller than the surface refractive power Pn.sub.s in a plane perpendicular to the main meridional plane (Pn.sub.m

摘要： A pupil conjugate-coupling device in a projecting optical system includes a first projection lens system which forms an intermediate image of an image indicating element, a second projection lens system which projects the intermediate image onto a screen, said first and second projection lens systems having optical axes intersecting at a predetermined angle, and an optical element having structural periodicity positioned between the first and second projection lens systems. The optical element has a positive power and a prism function for deflecting a bundle of rays transmitted through the first projection lens system towards the optical axis of the second projection lens system to thereby couple pupils of the first and second projection lens systems. The optical element is deviated from an intermediate image forming position by a predetermined offset in the optical axis direction thereof.
