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 variable soft focus lens system particularly adapted for photography is disclosed. The lens system incorporates two lens groups, a first object side lens group having an image side, rearmost surface convex to the image side, and a second, image side lens group having an object side, foremost surface concave to the object side. An airspace separating the first and second lens group has a meniscus shape concave to the object side. A good quality soft tone image having undersirable aberrations well within tolerable limits, is attained by shifting at least the second lens group along the optical axis relative to the first lens group whereby the airspace separating the two lens groups and a spherical aberration of the entire lens system is varied. An image does not lose proper focus while the spherical aberration of the system is varied. The second lens group has a refractive power within specified limits in relation to the refractive power of the entire lens system.

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.
