摘要： A laser beam output from a semiconductor laser light source 1 is transmitted through a cover glass 2 in the optical axis Z direction, is incident on a molded lens 4 in a state of divergent rays, is converted into convergent rays by the molded lens 4, and is applied onto a recording face 5 of the optical recording medium. A diaphragm 3 is arranged. An area of each lens surface onto which a luminous flux of the laser beam restricted by the diaphragm 3 is applied corresponds to an effective area. The following expression (1) is satisfied: d1−d0≧0.04 mm (1) where d0 denotes an effective aperture of one of the lens surfaces, and d1 denotes an outer diameter of the one of the lens surfaces.

摘要： A variable power optical system is provided and includes a positive first lens group, a negative second lens group, a positive fifth lens group, a positive third lens group, and a negative fourth lens group containing first to third sub lens groups, in order from the side of an object. The second lens group is moved, thereby performing variable power and the third lens group is moved, thereby correcting image surface variation caused by the variable power and performing focusing. The fourth lens group is fixed at the variable power time and the focusing time. To correct image blurring, only the second sub lens group is moved in a direction perpendicular to an optical axis. Accordingly, a sufficiently good image blurring correction function can be exerted and a simple and compact configuration as a whole can be implemented.

摘要： A zoom optical system includes a function of preventing blurring of an image due to movements, such as shaking of the zoom optical system, by moving a lens element of the third lens group, in order from the object side, of four lens groups in a direction that is perpendicular to the optical axis in order to correct for movements of the zoom optical system that would otherwise create a blurred image. The second lens group from the object side has negative refractive power and the other three lens groups have positive refractive power. The second and fourth lens groups move along the optical axis during zooming. The zoom optical system satisfies certain conditions related to the configuration of the lens elements and lens groups of the zoom optical system in order to prevent blurring and to provide a compact zoom optical system having excellent correction of aberrations.

摘要： A zoom lens includes a function of preventing blurring of an image due to movements, such as shaking of the zoom lens, by moving the second lens group, in order from the object side, orthogonally to the optical axis in order to correct for blurring of an image due to movements of the zoom lens. The zoom lens includes a first lens group having negative refractive power, a second lens group having positive refractive power, and a third lens group having positive refractive power. The first and second lens groups move along the optical axis during zooming, as does the third lens group in all but one embodiment of the invention. The zoom lens satisfies certain conditions related to the configuration of the lens elements and lens groups of the zoom lens in order to prevent blurring and to provide a compact zoom lens having excellent correction of aberrations.

摘要： An objective lens having no more that two lens elements with refractive power is disclosed for reading or writing at high density on a recording medium. The first lens element, in order from a light source side, is biconvex and includes at least one aspheric surface so that it is individually well-corrected for spherical aberration. The second lens element is of a meniscus shape with its concave surface on the recording medium side of the objective lens. If the objective lens is used without a cover glass at the recording medium, the convex surface of the second lens element is made to have an aplanatic surface, which is a surface that is capable of changing the convergence or divergence of a cone of rays without introducing any spherical aberration, coma or astigmatism. Whether or not there is a cover glass at the recording medium, the following condition is satisfied 0.8
