摘要： In a multibeam scanning optical apparatus of a type where two parallel lines are simultaneously scanned by two laser beams irradiated from two semiconductor lasers, stable images are formed on the scanned surface by the two laser beams and the cost is reduced. The two laser beams irradiated from the two semiconductor lasers are directed substantially in the same direction through a beam splitter and then shaped by a condenser lens into two luminous fluxes whose optical axes are substantially parallel to each other. In another arrangement, the semiconductor lasers are directly secured to a surface of the beam splitter by use of an ultraviolet setting resin.

摘要： An acoustooptic device is structured by providing an interdigital transducer in which arch-shaped electrode fingers are interdigitated so that the interdigital transducer is circular or annular in shape as a whole, on an optical waveguide which is circular when viewed from the front. This acoustooptic device is used as a diffraction optical device on which light is incident from the front. When an alternating voltage of a predetermined frequency is applied to the interdigital transducer by an oscillator, a concentric acoustic compressional wave is generated on the optical waveguide. The concentric acoustic compressional wave diffracts the incident light, so that the diffraction optical device functions like a lens and converges the luminous flux.

摘要： An optical device comprises an optical lens and a mounting assembly for securing the optical lens to a support surface. The optical lens has a longitudinal axis and has first and second projections; the mounting assembly includes a clamp member which has a clamp surface and depresses the optical lens downwardly through contact of the clamp surface with the optical lens so as to mount the optical lens on the support surface. The clamp member is formed, on the clamp surface, with first and second holes engageable with the first and second projections of the optical lens, respectively; the second hole is an elongated opening extending in the longitudinal direction of the optical lens.

摘要： A laser diode array unit for use in laser beam scanning optical apparatus and the like. The laser diode array has plural light emitting sources to be drivingly controlled independently of each other. The laser diode array is so disposed as to permit laser beams emitted from the light emitting sources to be incident to a collimator lens. On an optical axis between the laser diode array and the collimator lens is disposed a beam splitter for splitting the laser beams emitted from the light emitting sources into image light and monitor light. A magnifier lens and a photoreceptor element are arranged on the optical axis so as to allow incidence of monitor light oriented to advance in a direction perpendicular to the direction of advance of image light.

摘要： A light amount correcting interference membrane having almost constant thickness and characteristic for increasing transmissivity corresponding to an increase of incidence angle of a laser beam is provided on a scanning light path extending from a rotary optical deflector to a recording medium in a scanning optical system. The laser beam deflected by the rotary optical deflector for scanning the recording medium is transmitted through the light amount correcting interference membrane wherein the scanning velocity of the laser beam reaching the peripheral portion of the recording medium is faster than that of the laser beam reaching the central portion, and an incidence angle becomes large and transmissivity becomes high.

摘要： A drawing method for forming a reflective curved surface by pressing a metal plate fitted in a fixed die with a movable die. The fixed die is composed of a lower die and a core, and the movable die is composed of an upper die and a presser. During the drawing, the metal plate is pressed to have a compressed border portion between a non-pressed portion and a curved surface pressed portion. It is the most desirable to compress the border portion to have a thickness which is 70% of the thickness of the metal plate before drawing.
