摘要： A projection lens comprises 5 lenses in 5 groups including: a first-group lens that is a positive lens; a second-group lens that is a positive lens having the largest positive power (the inverse number of focal length) in the whole lens system; a third-group lens that is a positive lens; a fourth-group lens that is a positive lens; and a fifth-group lens that is a negative lens with its concave surface facing a screen side, in order from the screen side, wherein each lens of the first, third, fourth and fifth groups has at least one aspheric surface. The distance between the first-group lens and the second-group lens is relatively short, and the positive power in the fourth-group lens is relatively high. In the projection lens, an optical focal shift due to the temperature change in the fifth-group lens is hardly caused, and therefore a projection lens with minimal distortion aberration can be provided at a low cost.

摘要： The present invention provides a zoom lens that suppresses the generation of unnecessary light and is suitable for a projection lens. The zoom lens is used as a projection lens of a projector in which a prism is located between the projection lens and a spatial optical modulating element B. A lens closest to the spatial optical modulating element B is a meniscus positive lens whose convex surface faces a screen. A refractive index of the meniscus positive lens is 1.75 or more.

摘要： The present invention provides a projection lens for projecting light from a light source onto a screen to form a magnified image, including two joined lenses, each of which includes a negative lens and a positive lens. The difference in the refractive index and the Abbe number between the negative lens and the positive lens in each of the joined lenses and the partial dispersion ratio of the negative lens and the positive lens of the second joined lens are specified. Thus, a large angle of view and a long back focal length can be achieved while satisfying distortion aberrations, telecentric properties and magnification chromatic aberrations.

摘要： Provided is a method for making a thin film on a lens holder to reduce a reflection of light caused by an index difference between a refractive index of air and a refractive index of a lens-barrel of the lens holder. The thin film is formed by dipping the lens holder into a solution of a solvent and a fluororesin compound or by dripping the solution onto the lens holder. The lens holder is removed from the solution. Then, the solvent is removed to thereby form a thin film of the fluororesin compound on the lens holder.

The light entrance surface (11) has a first light entrance surface (111) and a second light entrance surface (112).
