摘要： In a scanning optical system, a partial light blocking member having an annular light blocking part (for blocking off part of the incident laser beam entering the annular area around the central axis of the laser beam) is placed on an optical path between the laser light source and the polygon mirror. The scanning optical system including such a partial light blocking member is installed in a printer. By the effect of the partial light blocking member, the intensity of side lobes (several rings of light accompanying the main beam) is prevented from exceeding a threshold value even when optical surfaces of an imaging optical system of the scanning optical system have certain microscopic undulations, by which black stripes occurring in halftone printing can be eliminated.

摘要： An objective lens for recording data to and/or reproducing data from first and second optical discs. The objective lens is provided with at least one surface including a plurality of annular zones divided by steps. The steps has functions of phase shifting a wavefront of light passing through the plurality of annular zones so that a beam spot formed at a converging point of an average wavefront of the wavefront phase shifted by the steps is used for the first and second optical discs. The plurality of annular zones of the at least one surface includes at least one annular zone structure which includes first and second annular zone groups, each of which has at least three steps for phase shifting the wavefront in a first direction, and a first return step which is a step formed at a boundary between the first and second annular zone groups. The first return step phase shifts the wavefront in a second direction opposite to the first direction. An absolute value |Δψ1| of a phase shifting amount of the first light beam given by the first return step satisfies a condition: 6π

摘要： The invention provides a sample observation method capable of understanding the three-dimensional shape of a sample in a wider range. The observation method of the invention calculates heights (height differences) in the whole domain of an image, from plural sheets of images of different field-of-view angles, being in focus over the whole image, attained by means of the focal depth expanding function to thereby create a map (Z map) of the height information by each pixel, and displays a three-dimensional image as a bird's-eye view. The method also displays to superpose a Z map attained from image signals reflecting the surface structure on a Z map attained from image signals reflecting the composition information with different colors, which makes it possible to clearly understand the spatial distribution of a substance of unique composition inside the sample.

摘要： A single element objective lens for an optical disc drive converges a laser beam, which is emitted by a laser source, on a data recording surface of an optical disc through a protective layer of the optical disc. One surface of the objective lens is divided into a central area including an optical axis thereof and a peripheral area surrounding the central area. The peripheral area is provided with a diffraction lens structure formed by a plurality of concentric annular zones including minute steps. The central area is a continuous surface having no stepped portions. The diffraction lens structure compensates for variation of converging characteristic of the objective lens due to a change of a temperature.

摘要： A scanning drawing apparatus includes a light source, a beam separator for dividing the laser beam into a drawing beam and a monitor beam. A drawing optical path through which the drawing beam travels, and a monitor optical path through which the monitor beam travels are defined. The drawing beam passed through the drawing optical path and the monitor beam passed through the monitor optical path are combined by a beam combiner, and then deflected by a scanning deflector. The deflected beams pass through a scanning lens to form beam spots on an image surface and a monitor scale that is equivalent to the image surface, respectively. The monitor optical path has a different optical path length from the drawing optical path and/or effective diameters of optical elements in the monitor optical path is different from effective diameters of optical elements in the drawing optical path. A deviation of the beam spot of the drawing beam on the image surface due to an inclination or a shift of the light source is equal to a deviation of the beam spot of the monitor beam on the monitor scale in terms of directions and amounts.
