摘要： 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.

摘要： The film mirror has sequencial layers of a hard coat layer, a resin layer and a reflective layer. The hard coat layer has an absorber and the absorber is a triazine absorber or an inorganic UV absorber. Such a mirror has high specular reflectance without delamination even after long-term irradiation by sunlight because of the specific absorbers used in the hard coat layer.
