摘要： PROBLEM TO BE SOLVED: To obtain a light flux branching element arranged in an imaging optical path and with which increasing of a lens total length can be reduced when branching part of the imaging light flux. SOLUTION: A light flux branching optical system, which separates between the light flux for imaging and the light flux for detecting the focusing position by a pupil division method, is constituted by at least two prisms having an air gap therebetween. Where the side onto which the light flux before division is emitted is a first side of the first prism onto which the light flux before division is emitted is a first side, and the side on which the air gap is formed is a second side, a light flux dividing film is provided to the second side, which transmits the light flux required for imaging and to which a function to divide the light flux required for detecting the focusing position by reflection. This reflection is the first reflection. In addition, the divided light flux required for detecting the focusing position subject to second reflection by total reflection on the first side is directed again to the second side. On the second side, third reflection is made by total reflection additionally. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PURPOSE: To make a light beam suitable for use in an optical recording/device by converting the light beam of a laser diode, which emits the light beam diverging with an elliptic section, to a light beam having a circular section. CONSTITUTION: Light emitted from a laser diode 10 is approximately collimated by a condenser lens 14. The angle of divergence in the direction parallel with the surface of paper is corrected by prisms 18 and 20 so that it is approximately equal to a small angle of divegence in the direction perpendicular to the surface of paper. The condenser lens 14 is controlled by a gear 27, and prisms are rotated around an axis 22 of rotation and are controlled. Light which passes prisms 18 and 20 controlled in this manner becomes a collimated light beam having a circular section. Thereafter, it is sharply focused on the surface of an object by a condenser lens 28 in accordance with a purpose.

摘要： PURPOSE:To accurately and surely detect the focus error by constituting a device so that a division line in the direction parallel with the diffraction direction of a diffracting device is parallel with the minor axis direction of reflected light from a shaping optical device. CONSTITUTION:The laser light emitted from a semiconductor laser 11 as the light emitting device which emits light having an approximately elliptic intensity distribution is transmitted through a diffraction element 12 as the diffracting device and is converted to parallel rays by a collimator lens 13. Since the minor axis direction on the diffraction element 12 of reflected light from an optical disk 16 and the direction of a division line l1 coincide with each other, a focus error signal FES is scarecely affected even in the vicinity, where the beam of reflected light is approximately linear, on the element 12 as shown by a line P because of defocus due to astigmatism generated by a shaping prism 14 even if the division line l1 is slightly inclined or deviated. Zero-crossing does not occur in the focus error signal though the spot is linear.

摘要： PURPOSE: To make it possible to obtain a high resolution by excluding the non- sharpness of focus caused by optical path difference by installing an anamorphic additional device composed of a flat face and a non-focus optical path expander in an optical system. CONSTITUTION: A laser beam becomes the incident light of an anamorphic optical path expander composed of wedge type prisms 17 and 19, and two wedge type prisms are respectively arranged so as to have included angles in mutual opposite directions to an optical axis 18. The width of beam parallel to scanning direction is increased inside the optical path expander by the anamorphic optical path expander 12 but the width of beam in the direction of output light from the optical path expander parallel to web inserting direction is not changed. then, the output light is made incident to an optical path expander 13 which does not change the cross-sectional form of beam, the optical path expander 13 returns the focus of laser beam, which is temporarily made infinitely far by the 2nd objective lens of a basic optical system 11, to be infinitely far again and a mirror wheel 22 is irradiated with the laser beam. Then, this laser beam is made incident to a concave mirror 21 and focused on a scanning plane 23. Thus, the out-of-focus of scanning beam caused by the optical path difference, etc., on the scanning plane of material web is prevented.
