    摘要： The present invention provides a piezoelectric actuator mechanism that is suited for automatic operation in the adjustment of a mirror holder in an optical system, or in the positioning of a movable table of a linear stage, that has a short entire length, and is capable of performing a compact and high-precision position/angle adjustment and positioning. The piezoelectric actuator mechanism comprises: a screw-driven feeding mechanism that is comprised of a feed screw 11 and a feed screw nut 14; a disc-shaped rotor 17 mounted on the rear-end face of the feed screw nut 14; an ultrasonic motor 18 having a piezoelectric vibrator 19 that comes in contact with the circumference face of the rotor 17; and a driven mounting portion that is pressed against the leading end of the feed screw 11 by spring force, and displaced and positioned by the feeding operation of the feed screw. The driven mounting portion can be made to be a mirror holder 1 to be used in an optical system, or a movable table 21 of a linear stage, for example.

    摘要： An optical element (20) is formed by bonding the faces of first to fourth triangular prisms (21, 22, 23, 24) that form the apex angle, wherein bonding faces (21a, 22b) of the first and second triangular prisms, bonding faces (22a, 23b) of the second and third triangular prisms, bonding faces (23a, 24b) of the third and fourth triangular prisms, and bonding faces (24a, 21b) of the fourth and first triangular prisms are respectively bonded through an optical thin film. Each optical thin film allows the incident light to pass through, or reflects the incident light, depending on the polarization state. The optical element (20) splits an optical path at a first position of the optical thin film, and combines optical paths at a second position of the optical thin film.

    摘要： A broadband non-polarizing plate beam splitter which can be used in a wide wavelength band, and which can achieve improved yield and lowered manufacturing costs with little dependence on angle of incidence and with a small number of films.
    A beam splitter for splitting a beam by inputting a light beam, wherein both main surfaces of a flat plate-shaped transparent glass substrate are optically polished, and one main surface of the transparent glass substrate has provided thereon: a wavelength band expanding film; a metallic film provided on the wavelength band expanding film; and a non-polarizing film provided on the metallic film. The light beam is non-polarized by means of the non-polarizing film when said light beam is input to the beam splitter, and the desired transmittance and reflectance are achieved when the non-polarized light is input to the metallic film. Thus, in terms of the wavelengths of light transmitted by the metallic film, the band in which the beam splitter can be used is expanded by the wavelength band expanding film.
