Abstract: Disclosed is a digital microscope system capable of controlling two or more microscope units with a controlling unit. The digital microscope system includes (i) two or more microscope units, (ii) a camera interface, (iii) a controlling unit and (iv) a light output device. The microscope unit includes a lens tube, a digital camera, a light terminator and a stand. The camera interface includes two or more camera interface (I/F) channels and a camera interface channel selector. The controlling unit includes a memory, a display device, a CPU (Central Processing Unit) and a power supply.

Abstract: An automatic lens blocking apparatus having a tracer and a lensmeter therein, for adhering a block to a lens by using a robot arm, is disclosed. The automatic lens blocking apparatus comprises: a tracer for obtaining data on a shape of a glass frame and data on a center of the glass frame; a lensmeter for obtaining data on an optical center of a blank lens by measuring physical property of the blank lens; an image camera part for obtaining an image of a shape and a position of the blank lens; and a blocker (a) for determining a blocking position to which a block is adhered on the basis of (i) the data on the shape of the glass frame and the data on the center of the glass frame obtained from the tracer, (ii) the data on the optical center of the blank lens and physical property of the blank lens obtained from the lensmeter and (iii) the image of the shape and the position of the blank lens obtained from the image camera part, (b) for moving the block and (c) for adhering the block to the blank lens.

Abstract: A lens edger which is capable of measuring the curvature of an eyeglass lens is disclosed. The lens edger includes a carriage which rotatably fixes a pair of lens fixing shafts and moves the position of the lens fixing shafts clamping a lens to be processed; a lens rotation motor for rotating the lens fixing shafts; a carriage driving means for moving the carriage; and an apparatus for measuring a curvature of the lens.

Abstract: A topographer for mapping the central portion as well as the peripheral portion of the corneal surface is disclosed. The topographer includes a chart image generating part for producing a chart image to fixate the gaze of an eye under test; a measuring light source for projecting concentric ring-shaped measuring lights to the cornea of the eye; a light detector for detecting the image of the measuring light reflected from the cornea; and a vertex measuring optical system.
