摘要： A projection image display device is disclosed in which a trapezoidal distortion and/or aberration are restrained when an image is enlarged and projected obliquely onto a screen. An image generator is connected to an optical system base in such a manner that at least an inclination thereof (on an axis parallel to X axis) with respect to a vertical line and a distance thereof in forward and backward direction (Z axis direction) can be adjusted by an adjusting mechanism. Further, a projecting lens 2 as a first optical system and a free-form curved surface mirror as a second optical system are fixed to the optical system base. The free-form curved surface mirror is rotatable (on an rotary axis parallel to X axis) with respect to the vertical line at a substantial center of the free-form curved surface mirror.

摘要： An image that has been displayed on the display screen of an image generator is first passed through a projection lens section consisting of a front group and a rear group. Next after being reflected on the reflecting surface of a free-form surface mirror, the image is further reflected by a planar reflecting mirror and then obliquely projected from the lower section of a projection screen onto the screen. The front group of the projection lens section is provided for enlarging the image. In order to correct aberration due to oblique projection onto the projection screen, the rear group uses a free-form surface lens that forms a concave shape with respect to the exit side of light from the lens. The free-form surface mirror corrects trapezoidal distortion due to oblique projection onto the projection screen. The free-form surface lens in the rear group of the projection lens section can accommodate changes in environmental conditions by using one edge as a reference edge and rendering the other edge expandable. The free-form surface mirror can likewise use one edge as a reference edge and render the other edge expandable. For adjustment, the free-form surface mirror can also be pivoted about the reference edge.

摘要： Images that are bright even on the periphery of a transmissive screen are obtained by reducing reflection loss of the screen when the screen incident angle of the image light entering the upper left and right ends of the screen increases. Incident-side prisms (10), each having at least a plane-of-incidence (c) onto which light comes in, an exit face (d) from which the light that has come in from the plane-of-incidence exits after being refracted, and a refractive face (e) on which the light that has exited from the exit face is refracted and then guided to the image-viewing side of the Fresnel lens sheet (6), are provided in the range where the incident angle of the incoming light becomes equal to or greater than approximately 40 degrees.

摘要： An opaque area is formed in a sidewall portion of a susceptor by stacking a material that is transparent to flash light and a material that is opaque to the flash light to form the sidewall portion or coating a surface of the opaque material with the transparent material. A top surface of the opaque area in the sidewall portion of the susceptor is designed to have a predetermined positional relationship with a top surface of a substrate; the top surface of the opaque area is set at the same position as that of the top surface of the substrate or higher than the top surface of the substrate by a predetermined height. Thus, obliquely incident flash light is absorbed or irregularly reflected by the opaque quartz portion, surrounding an excavated portion of the susceptor.

摘要： A light-shielding film for exposure light is formed on one principal plane of a transparent substrate made of quartz or the like that serves as a photomask substrate. The light-shielding film can serve not only as the so-called “light-shielding film” but also as an anti-reflection film. In addition, the light-shielding film has a total thickness of 100 nm or less, 70% or more of which is accounted for by the thickness of a chromium compound that has an optical density (OD) per unit thickness of 0.025 nm−1 for light having a wavelength of 450 nm. In the case where the photomask blank is used for fabricating a mask designed for ArF exposure, the thickness and composition of the light-shielding film are selected in such a manner that the OD of the light-shielding film is 1.2 to 2.3 for 193 or 248 nm wavelength light.
