CONSTITUTION: This equipment comprises a light emitting means 13 constituting a light source 12 on the optical path, a holding station 15 receiving an optical system 10 under inspection, an array 16, and means 17 receiving an image which can be observed in the downstream of the array 16. The equipment further comprises a data processing means 18 utilizing the image through phase detection, and a separator element 26 constituting a half-reflective surface on the axis of optical path between the light source 12 and the holding station 15. The image receiving means 17 is disposed on the side part while being arranged with the separator element 26. The data processing means 18 comprises a light beam plot program, and a calibration means where the theoretical aberration and the manufacturing aberration of the separator element 26 are taken into account. According to the arrangement, an arbitrary optical system 10 or a plane can be inspected accurately.

Abstract: PURPOSE: To improve visual acuity of a person suffering from macular degeneration by using a positive ophthalmological lens of high magnification placed in front of an eye and a negative intraocular lens of high magnification embedded after removing the crystal lens and making at least each one face of both lenses a rotary aspheric surface. CONSTITUTION: This optical system is composed of a positive ophthalmological lens 10 of high magnification placed in front of an eye to be treated and a negative intraocular lens 11 of high magnification embedded in the eye 12 after removing the crystal lens, and at least each one face 21, 25 of both lenses 10, 11 is a rotary aspheric surface. The generating line of the rotary aspheric surface is preferably a conic section, and a conic section containing rotary aspheric surface can be expressed by Formulae I and II. In Formula I and II Z is the coordinate along the axial line, and r =X +Y where X and Y are coordinates on the plane perpendicular to the axial line, R1 and R5 are the radii of curvature of the plane in the center, and K1 and K5 are conical constants that can derive the planes of desired conic section bus line from the basic spherical plane of radii R1 and R5. The use of appropriate conical constant K1 and K5 gives ellipse for the generating line of the front face 10, 11 when the image formed on retina is of good quality.

Abstract: PURPOSE: To simply, exactly and economically settle a lens to be used within the contour of any die plate by providing the system with an adsorber support, and fitting a die plate support, with which the die plate to be overlapped on the lens can be freely attached and detached, to a barrel attached onto an arm so as to be freely rotated. CONSTITUTION: In the state of setting an arm 14 at an extending position, a lens 11 is centered through a watch hole 18 by using a table 12 while considering the parameter such as the pupil range of a relevant person. Next, in order to place a die plate 22 on a die plate support 21 of a barrel 20, the barrel, 20 is rotated with an axis A2 as a center for locating the die plate support 21 closest to the watch hole 18, and when the arm 14 is returned along an arrow F with an axis A1 as a center later, the die plate 22 is overlapped onto the lens 11. Therefore, the settling of the lens into the contour of the die plate 22 is visually examined later. Next, the arm 14 is held up and when the arm 14 is returned again after the barrel 20 is rotated by half so as to position an adsorber support 15 closest to the watch hole 18, a grasping/holding mechanism 13 is abutted on the lens 11 and fixed.

Abstract: PURPOSE: To measure an inter-pupil range by providing the subject device with a liquid crystal matrix device at a window part for graticule display on a front panel and providing this matrix device with a digital address generator and a controller for controlling the display of gradicules. CONSTITUTION: Window parts 15-18 are arranged on the front panel, and these window parts are composed of a liquid crystal matrix. A logic device 20 is selectively connected to the row and column input parts of matrix at the window parts 15 and 16 and the row input part of matrix at the window parts 17 and 18. A control keyboard 21 consists of a state change control address generator together with the logic device 20. The matrix column address signals of the window parts 15 and 16 are received so that a dark vertical line 16a can be watched. The address signals can be changed by using the keyboard 21 and this is performed until the line 16a passes through the reflecting part of a light source on the cornea. The respective address signals are corresponding to distances from the centers of pupils of relevant eyes to the symmetric vertical axis of the front panel and the total of both the distances become the inter-pupil range. The inter-pupil range and the distances from the symmetric vertical axis to the left and right pupils are displayed by the logic device 20.

Abstract: PURPOSE: To optionally minimize maximum thickness by defining a system for changing a refractive index by a rule that the absolute value of optical magnification of a lens is sharply larger than geometric magnification at the time of calculating the optical magnification by using a refractive index on the optical axis of the lens. CONSTITUTION: The maximum thickness of a single focus glasses lens having a partially spherical convex face 10 on one side and a concave face 11 and capable of changing its refractive index in the diameter direction from the optical axis X of the lens to its periphery is minimized. The system for changing the refractive index is defined by the rule that the absolute value of optical magnification of the lens is sharply larger than geometric magnification at the time of calculating the optical magnification by using the refractive index on the optical axis X of the lens. The absolute value of the optical magnification is at least 1.5 times the geometric magnification. Consequently, the single focus glass lens allowed to be easily worked and capable of sufficiently correcting astigmatism and field curvature aberration and suitably reducing the maximum thickness is manufactured.

Abstract: PURPOSE: To obtain the excellent distribution characteristics of a synthetic material especially around a central insert by constituting one layer (engineering layer) among concentric layers of a fabric product constituted of yarn made of an engineering material and/or a classical material and constituting the other one layer (matrix) among them of a thermoplastic material to allow the same to be present in the peripheral part of an assembly. CONSTITUTION: A deformable composite structure 10 is elongated as a whole and contains a plurality of layers concentrically centering around the core 11 extending over the total length of the structure 10. These layers consist of at least one layer (engineering layer) 12A constituted of a fabric product constituted of yarn made of a material generally called an engineering material such as carbon, glass or aramide and/or a classical material such as a vegetable material, an artificial material, a synthetic material or a metal material and at least other one layer 12B, 12'B (matrix) made of a thermoplastic material. The matrix 12B is present at least in the periphery of an assembly.
