    摘要： In an image recording apparatus 1 which records an image on a recording medium 9 by moving an optical head 10 while rotating the recording medium 9 held by a holding drum 7, a photodetector 2 having a plurality of photodetector elements 21 is provided in a range of movement of the optical head 10. In correcting beam intensity, the optical head 10 is positioned so precisely that the photodetector 2 can receive the signal light beams. This constitution makes it possible to detect signal light beams from the light modulator with high S/N ratio as compared with a conventional case where one photodetector element sequentially receives the signal light beams, and therefore possible to correct the beam intensities with high accuracy.

    摘要： An apochromatic lens system is corrected for chromatic aberration at three wavelengths. The apochromatic lens system includes a plane glass and a plane lens which are interchangeable with each other. When the plane glass is disposed on the optical axis of the lens system, the plane glass cooperates with the lens system to correct for chromatic aberration at first and second wavelengths. When the plane lens is disposed on the optical axis instead of the plane glass, the plane lens cooperates with the lens system to correct for chromatic aberration at the first wavelength and at a third wavelength.

    摘要： An apochromat optical system for a photoengraving process comprises a first lens group which includes a first lens having a positive power, a second lens made of Kultz flint glass having a negative power and a third lens in the form of a meniscus having a positive power. The first to third lenses are successively disposed in order starting from the object side. A second lens group includes the substantially same configuration of lenses as in the first lens group. The lenses of the first and second lens groups are approximately symmetrical with respect to the stop. Accordingly, the system has a high aperture ratio and small curvature of a saggital and meridional image field which can reduce an astigmatic difference in a peripheral part of an image.

    摘要： A lens system operable with two or three colors comprises a front lens system disposed on the object side relative to a stop and a rear lens system disposed on the image side relative to the stop. The front lens system includes first to third lens groups, while the rear lens system includes fourth to sixth lens groups. Each of the front and rear lens systems includes two meniscus lenses. The meniscus lenses have a concave surface and a negative power. Accordingly, average image points with respect to two or three wavelengths substantially coincide with each other, while the image fields coincide with each other within the range from the vicinity of the optical axis to image peripheral portion.
