    摘要： An illumination optical system includes a light source for emitting a plurality of different colors of light, a plurality of rotating optical scanners, and a plurality of scanning lenses. Each of the optical scanners has a reflecting surface that is formed helically around a cylindrical body. The different colors of light enter the respective reflecting surfaces in the direction parallel to the rotation axis, are reflected therefrom, and pass through the scanning lenses, so that each color of light is magnified and then scans the region to be illuminated sequentially. This makes it possible to provide an illumination optical system that can improve scanning linearity, lower noise because of its reduced wind resistance, and achieve reduction in the cost and power consumption.

    摘要： A light quantity distribution control element includes a substrate of 20 mm×20 mm×3 mm made of a material that transmits light, such as optical glass or acryl, and a antireflective structure provided on a surface of the substrate. As the antireflective structure, a conical antireflective structure of a pitch of 0.15 μm (periodic structure having conical convexities) is formed. This corresponds to a antireflective structure having a pitch of a wavelength or less in the ultraviolet band (150 nm to 400 nm) at the time when ultraviolet light is used as incident light.

    摘要： A wide-angle imaging optical system includes a refractive optical system (3), a reflective optical system, and an image-forming optical system (5). The reflective optical system includes a first reflection surface (1) that directly reflects rays of light from an object, and a second reflection surface (2) that reflects rays of light from the first reflection surface (1). An open portion is provided between the first reflection surface (1) and the second reflection surface (2), and rays of light from the object enter the open portion. A light-transmitting portion (2a) is provided in the second reflection surface (2) and transmits rays of light that have entered the refractive optical system (3). An aperture (1a) is provided in the first reflection surface (1) and allows rays of light from the second reflection surface (2) and the refractive optical system (3) to enter the image-forming optical system (5).
