    Abstract: A zoom lens is a projection lens which is composed of a negative first lens group, a negative second lens group, a positive third lens group, a negative fourth lens group, a fifth lens group, and a positive sixth lens group in order from the enlargement conjugate side, and changes magnification by changing the intervals between the lens groups. At least the second, third, and fifth lens groups move when the magnification is changed, and the third lens group moves from the enlargement conjugate side to the reduction conjugate side when the magnification is changed from a telephoto end to a wide angle end. An aperture stop is disposed between the surface closest to the reduction conjugate side of the third lens group and the surface closest to the enlargement conjugate side of the fifth lens group, and is approximately telecentric on the reduction conjugate side.

  • Variable-focal-length projection lens system and projection apparatus
    Patent number: 8699139
    Abstract: A variable-focal-length lens system for projection which achieves focusing by movement of the entire system has a second to a fourth lens group as focal-length-varying lens groups and a first lens group as a distance-compensation lens group. The second to fourth lens groups individually move in the optical axis direction to vary the group-to-group distances so as to vary the focal length of the entire system. During focusing, the first lens group moves in the optical axis direction such that, as the projection distance varies from a remote distance to a close distance, curvature of field varies to the under side.
