摘要： Disclosed is a wide-angle lens having a viewing angle of more than 130°. The wide angle lens has a front group, an aperture, and a rear group arranged in this order from an object side to an image side. The front group has a first lens as a negative lens, a second lens as a negative lens, and a third lens as a positive lens arranged from the object side to the image side. The rear group is a cemented lens having a positive power when two lenses are bonded to each other. The wide-angle lens constitutes an image forming system with the five lenses as a whole, the first lens and the second lens of the front group are aspherical lenses, and the third lens is a spherical lens.

摘要： A wide angle lens whose field angle exceeds 160 degrees, includes a front group, an aperture stop, and a rear group arranged in this order from an object-side toward an image-side. The front group includes a first lens (negative meniscus) whose convex surface faces the object, a second lens (negative), a third lens (negative), and a fourth lens (positive), arranged in this order from the object-side toward the image-side. The rear group includes a fifth lens (positive), a sixth lens (negative), and a seventh lens (positive), arranged in this order from an aperture-side toward the image-side. The fifth and sixth lenses are combined, forming a cemented lens having positive refractive power. The fifth and sixth lenses are made of materials having Abbe numbers of greater than or equal to 50 and less than or equal to 30, respectively. A surface of the seventh lens facing the image is aspheric.

摘要： A projection optical apparatus capable of providing high image quality and having a reduced size is disclosed. The projection optical apparatus includes a light valve and a projection optical system including a first optical system having a transmissive-refractive element and a second optical system having a reflective-refractive element. An image formed on the light valve is projected by the projection optical system on a projection surface. The optical axis in the first optical system is folded both vertically and horizontally. The first group of the first optical system is contained in a space (dead space) whose lower limit is defined by a lower edge of the second optical system, thereby reducing the depth of the apparatus.
