    Abstract: An optical pickup incorporates a two-lens system with first and second lenses (13) and (14) being arranged in the following manner: the first lens has a first surface (15) to receive a laser beam radiated from a semiconductor laser and a second surface (16) to direct the laser beam transmitted from the first surface (15) towards the second lens (14); the second lens (14) has a third surface (17) to receive the light flux transmitted from the second surface (16) and a fourth surface (18) to direct the light flux transmitted from the third surface (17) towards an optical disc placed opposite thereto; and the first and fourth surfaces (15, 18) are used as a reference during positioning. The aberrations of the optical pickup are limited within a tolerable limit without incorporating a special device for that purpose even if errors arise in thickness of component lenses of a two-lens system constituting an element of the pickup.

    Abstract: A variable focus lens contains a conductive liquid material portion and an insulative liquid material portion in a cylindrical container and includes a first electrode which applies voltage to the conductive liquid material portion through a dielectric layer and a second electrode which directly contacts with the conductive liquid material portion, in which the dielectric layer is an anodized portion 22 made of a metal oxide formed by anodizing the first electrode.

    Abstract: The lens holder is for lenses (2,3) which are arranged on an optical axis of an optical measuring head which is constructed for the recording and/or reproduction of data. The holder has several reference surfaces (4a1,4b1) which in each case lie along the optical axes and the inclination of the lenses the lenses (2,3) for controlling the positions of the lenses to regulate the positions of the lenses along the optical axes and the inclination of the lenses. Independent claims are included for methods for producing a lens holder, and for a metal punch used for producing the lens holder.

    Abstract: PROBLEM TO BE SOLVED: To obtain a large zoom power, in a zoom lens using a liquid lens with small size.SOLUTION: The zoom lens 1 includes: a first lens group 10 which has two or more refracting surfaces 11a, 11b of which curvature changes according to the focal length and which gives a negative refracting power; and a second lens group 20 which is arranged on the image side 2 of the first lens group 10 and has a positive refracting power. The first lens group 10 has: two light transmitting members at least one of which can be deformed; and a type of light transmitting liquid medium sealed between those two light transmitting members, and the first lens group includes a first variable focus lens 11 having a negative refracting power.
