    摘要: In an exposure apparatus of the invention, for a spatial light modulator, each of a plurality of pixel portions fewer than the total number of the pixel portions is controlled with a control signal generated according to exposure information. Namely, a part of the pixel portions is controlled without controlling a whole of the pixel portions on the substrate. Thus, the number of pixels in the pixel portions is described, and transfer time of the control signal becomes short. This enables modulation speed of the laser beam to be increased and the high-speed exposure to be performed. An incorporated laser light source, in which the laser beams are incorporated and struck on the optical fiber, is preferable to the laser device. By adopting the incorporated laser light source, high brightness and high output can be obtained, and it is preferable to the exposure of the spatial light modulator. Since the fiber array is obtained with few optical fibers, it is low cost Since the number of optical fibers is few, the light-emitting region is further decreased when the optical fibers are arrayed.

    摘要: In a surveillance camera 2, an optical system unit for use in imaging is provided with a first lens 7, a second lens 8, a third lens 9, and a fourth lens 10, and a subject image is formed on a photoelectric surface 12 of an imaging element through a cover glass 11. The third lens 9 is an optical lens made of a nanocomposite material of the invention in which inorganic fine particles are dispersed. A thin film layer 15 that blocks UV rays is formed on a light incident surface of the third lens 9. After passing through the first lens 7 and the second lens 8, UV rays contained in subject light are blocked by the thin film layer 15 and therefore cannot enter the third lens 9.

    摘要: An objective optical system includes a diffractive optical element on the light source side of an objective lens for focusing incident light of three different wavelengths with two different numerical apertures onto three different optical recording media. The diffractive optical element is formed of two lens elements made of different materials that are cemented together at a diffractive surface. Three conditions are satisfied so as to achieve optimum imaging. The diffractive surface may be shaped so that the order of the diffracted light of the shortest wavelength λ2 having the largest diffracted intensity is different from the order of the diffracted light of the second wavelength λ2 having the largest diffracted intensity, and the order of the diffracted light of the first wavelength λ1 having the largest diffracted intensity is also different from the order of the diffracted light of the third wavelength λ3 having the largest diffracted intensity.
