摘要： An object of the present invention is to suppress an influence due to temperature change and various aberrations. It is a projection lens which projects an image on a surface of a screen (magnified side). A first group I having a negative refractive power and a second group II having a positive refractive power are arranged in order from a magnified side toward a reduced side. The first group I is configured to arrange a first lens and a second lens in order from the magnified side, and the second group II is configured to arrange a third lens to a seventh lens. The first and second lenses are a negative meniscus lens whose both surfaces are formed by the aspherical surface in which an area near an optical axis of the surface on the magnified side is a concave surface. The third lens is a cemented lens in which a bi-concave lens is cemented to the surface on the reduced side of a bi-convex lens. The fourth lens is a positive meniscus lens whose both surfaces are formed by the aspherical surface, and a convex surface of the positive meniscus lens faces toward the reduced side. The fifth lens is the cemented lens in which the bi-concave lens is cemented to the surface on the reduced side of the bi-convex lens. The sixth lens is a positive lens whose strong convex surface faces toward the reduced side. The seventh lens is the positive lens whose both surfaces are a convex surface.

摘要： A projection lens unit includes a main body; a lens fixed to the main body; and a hood disposed to one end of the main body close to a screen. The hood defines the outermost boundary of a view angle stretching with respect to the center of the lens and includes a light-shielding plate and a light-shielding barrel. When the shielding height of the light-shielding plate and the length of the light-shielding barrel are respectively represented by H and L, the shielding height H and the length L are set so as to satisfy the equation tan(α/2)=H/L, in relation to the view angle α. More particularly, these dimensions are set so as to satisfy the condition that the ratio H/L lies in a range from 0.74 to 0.94. The inner surface of the light-shielding barrel is subjected to surface treatment so as to absorb unnecessary light thereby, reflect it thereat, or scatter it thereat. To be more specific, the light-shielding barrel has scattering grooves disposed on the inner surface thereof.

摘要： This projection lens for a projection television includes coaxially in order towards the face plate of the CRT: a first lens of negative power, both of whose surfaces are aspherical; a second lens of positive power, at least one of whose surfaces is aspherical, formed of a plastic material; a third lens of positive power; a fourth lens of positive power, at least one of whose surfaces is aspherical, formed of a plastic material; and a back lens of negative power, which presents in the direction away from the face plate of the CRT a face of strongly concave curvature. The third lens is the strongest of the lenses in absolute power, and the second lens and the fourth lens have substantially the same optical characteristics, and are disposed in reverse orientation on opposite sides of the third lens. Certain conditions relating to lens parameters should be satisfied for acceptable optical performance. It is anticipated that the second lens and the fourth lens will be manufactured from plastic material by using the same metal mold for injection molding, which provides highly desirable cost economy for manufacturing setup.
