 A lens position adjustment system 10 permits adjustment of the position of a projection lens 5 relative to a projector for making a Scheimpflug adjustment. The projection lens 5 has an optical axis 6. The system comprises: a first support part 20 for fitting to, or forming part of, the projector, a second support part 40 for fitting to, or forming part of, the projection lens 5; and a connecting part 30. The connecting part 30 is pivotally connected to the first support part 20 and pivotally connected to the second support part 40 and configured to permit independent adjustment, such as by means of a gimbal or universal joint structure, of the second support part 40 relative to the first support part 20 about two axes of rotation 7, 8 which intersect, and are perpendicular to, the optical axis of the projection lens. |
