摘要： A variable soft focus lens system particularly adapted for photography is provided. The soft focus lens system includes at least two lens groups defining a meniscus shaped air space there between. The relative width of the air space can be variable by movement of one of the lens groups relative to the other. This movement can introduce a controlled amount of spherical aberration to provide within certain parameters a soft focus image with an acceptable Petzval sum and flatness of the image plane. Various embodiments of the present invention within the inventive parameters can be utilized and include both stationary and variable soft focus lens system.

摘要： A shadow mask is arranged to face a phosphor screen formed on an inner surface of a panel. A plurality of aperture columns are formed in parallel in the shadow mask. Each aperture column includes a plurality of apertures arranged in line at a predetermined interval. On both sides of each aperture column on the surface of the shadow mask facing the electron gun, stripe-shaped dielectric layers for acting on electron beams toward the apertures are formed respectively, and extend in substantial parallel with the aperture columns. The shadow mask is manufactured in such a manner that stripe-shaped insulating material layers are formed on the surface of a mask base material facing the electron gun, the mask base material is thereafter shaped into a predetermined shape, and the insulating material layers on the shaped mask are sintered.
