摘要： A single focus lens is composed of four lens components of negative, positive, negative and positive refractive power, respectively, in order from the object side. The first lens, in order from the object side, has a concave surface on the image side, and a stop is positioned between the first lens and the second lens. The second lens has a convex surface on the object side, the third lens has a concave surface on the object side, and the fourth lens has a convex, aspherical surface on the image side such that the refractive power of the fourth lens becomes weaker towards the edge of the lens. Specified conditions are preferably satisfied in order to provide favorable correction of aberrations.

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： An objective lens and an optical pickup device utilizing it are disclosed wherein the objective lens includes a specified aspheric surface profile having a discontinuity and a single specified diffraction optical surface so to provide a focusing effect which is usable with different optical recording media, such as a CD versus a DVD. By providing a single diffraction surface and an aspheric surface having a discontinuity, more freedom of design is achieved for the diffraction surface than would otherwise be possible. The objective lens according to the invention is designed so as to be both compact and inexpensive and enables recording/playback onto either type optical recording media using different wavelengths and different numerical apertures, depending on the recording medium used.

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.
