摘要： A mold with which a molded product in a desired shape with an aspherical curved surface is molded can be designed with high precision by correcting shape deformation of the molded product molded from the mold. A mold 10 in which use surfaces 16 of an upper mold 11 and a lower mold 12 are formed to be design curved surfaces of the optical lens in a spherical shape is prepared. A curved surface shape of the optical lens molded from the mold is measured, a measured value is approximated by an equation (1) which is an equation of an aspherical surface and a curved surface of the molded optical lens is specified as an aspherical surface. Information corresponding to an error between the curved surface of the optical lens specified by the equation of the aspherical surface and the above-described design curved surface is compiled into database for each of characteristics of the optical lens as correction information for molding the optical lens of which curved surface is in the spherical shape. By using the correction information compiled into database, design values of the use surfaces in the upper mold and the lower mold of the mold with which the optical lens of which curved surface in the aspherical shape is molded are corrected to design them.

摘要： An ophthalmic photographic device includes an illumination optical system for irradiating a fundus oculi of an eye to be examined with illuminating light, a photographic optical system to photograph fundus oculi, an indicator projecting optical system for projecting an indicator on the fundus oculi, and a focusing detection optical system which has a photoelectric converter receiving light of the indicator projected on the fundus oculi and detects focus information based on an output from the photoelectric converter. According to the present invention, the ophthalmic photographic device further includes a barrier filter for fluorescent photography which is used in fluorescent photography to cut off exciting light and to transmit fluorescent light from the fundus oculi and light having longer wavelengths than the fluorescent light over a predetermined wavelength range, and a barrier filter for infrared fluorescent photography which is used in infrared fluorescent photography to cut off exciting light and to transmit infrared fluorescent light from the fundus oculi and light having longer wavelengths than the infrared fluorescent light over a predetermined wavelength range. The barrier filters are adapted to be selectively used according to photographic conditions.

摘要： An aspherical ophthalmic lens having a positive refractive power, an axis of symmetry and a periphery includes front and rear refractive surfaces. The front refractive surface has a meridional plane and a sagittal plane that intersects the meridional plane. The sagittal plane has a sagittal plane curvature of .rho..sub.s, and the meridional plane has a meridional plane curvature of .rho..sub.m. A curvature difference Z, defined as Z=.rho..sub.m -.rho..sub.s, decreases from at least approximately 20 mm from the axis of symmetry in a direction toward the periphery. As a result, a thinner and flatter lens having superior optical performance is provided.

摘要： An aspherical eyepiece has a positive lens group and a correction plate positioned on the light incident side of the positive lens group and having an aspherical surface. The correction plate is positioned between the positive lens group and the front side focal plane of the positive lens group or in front of the front side focal plane of the positive lens group. Thus, although the eyepiece is constructed by a reduced number of optical members including an aspherical optical member, distortion can be favorably corrected even with a wide field angle.
