    摘要: An optical element has a first optical member which is a transparent body having two refracting surfaces and a reflecting, curved surface symmetric only with respect to one symmetry plane and a reference axis of which is present in the symmetry plane; and a second optical member which is a transparent body having two refracting surfaces and a reflecting surface and a reference axis of which is not present in the symmetry plane. One refracting surface of the second optical member is coupled to one refracting surface of the first optical member. The reference axis is defined by a ray passing an image center and a pupil center of an optical system including the optical element.

    摘要: An optical scanning device can scan two different types of optical record carrier (1; 25), requiring a scanning beam (15) having different numerical apertures. The device has two stops (33; 32) at different positions along the optical axis of the path followed by the radiation beam for both types of discs. The first stop (33) limits the numerical aperture of the radiation beam when scanning the first type of record carrier (1). The second stop (32) limits the numerical aperture when scanning the second type of record carrier (25).

    摘要: The present invention relates to a lithography apparatus using catadioptric exposure optics that projects high quality images without image flip. The lithography apparatus includes a reticle stage, a wafer stage, and a catadioptric exposure optics located between the reticle stage and the wafer stage. The catadioptric exposure optics projects an image from the reticle stage onto the wafer stage. The projected image has the same image orientation as the image from the reticle stage. In other words, the catadioptric exposure optics does not perform image flip. The reticle stage lies on a first plane and the wafer stage lies on a second plane, where the first plane is orthogonal to the second plane. In another embodiment of the present invention, the catadioptric exposure optics projects an even number of reflections. The projected image is of high precision and lacks aberrations such as perspective warping and obscured areas. The invention can be combined with a dual wafer stage and with a dual isolation system.

    摘要: In an optical pickup device, an objective lens unit includes a first lens, a second lens for converging a light beam which passed through the first lens on an information recording layer of a recording medium, and a second-lens-driving-use actuator for adjusting the distance between the first and second lenses. The second lens has a reflecting section for reflecting an outer part of the light beam which passed through the first lens and reached the second lens. Moreover, the optical pickup device includes a condenser lens, a cylindrical lens and a light receiving element for detecting a reflected light beam reflected by the reflecting section, and a control device for detecting the distance between the first and second lenses according to the result of detection and for controlling the second-lens-driving-use actuator according to the result of detection. With this structure, the occurrence of spherical aberration due to an error in the thickness of a cover glass of the recording medium and variations in the thickness of the objective lens is limited.

    摘要: The present invention provides a position-control device for a light modulation device, capable of easily performing a position-control operation. A position-control device is provided with a reference projection lens built therein capable of being commonly used, the reference projection lens projecting light combined by a crossed dichroic prism and forming a projection image, and having a predetermined optical characteristic. If the position of the optical axis is aligned once when the reference projection lens was built in, it is not necessary to align the optical axes every time the positions of liquid crystal panels are controlled and the replacement of the liquid crystal panels and the crossed dichroic prism is only required, whereby the position-control operation can be easily performed.
