摘要： A method of forming a microstructure array suitable for use in the production of a focusing screen used in a finder system of a camera. The focusing screen includes an optical material in plate form having on one surface of a plurality small lens portions that project in a regular array of equilateral triangles from the optical material and each of the which has concentric contour lines, with a central apex. A flat portion is formed between adjacent small lens portions and a constricted portion is formed in the middle portion of the inclined surface of each small lens portion, with an irregular pattern of finer asperities is formed on the surfaces of the small lens portions and the flat portion. The high and low spots can be reversed. The method of forming a microstructure array includes the steps of forming a fine pattern of elements on a layer of light-sensitive material capable of transforming a distribution of light intensity to a surface relief by exposing the layer through a microlens array to rays of light with an intensity distribution corresponding to individual elements of the fine pattern. The microlens array may be replaced with a group of pinholes.

摘要： A zoom finder can be provided which ensures high magnification and satisfactory view-finding without the need to increase the size. A positive lens which is movable along the optical axis is provided closest to the object side. A negative lens which is movable along the optical axis is provided on the eye-side of the positive lens. Zooming may be accomplished by the zoom finder by moving these lenses along the optical axis. A third lens is provided on the eye-side of the negative lens. The third lens is a negative lens which is fixed and has an eye-side surface which serves as a half-mirror. On the other side of this third lens is a parallel planar plate having an optical frame on one surface which indicates the imaging range. The parallel planar plate may be moved in a direction perpendicular to the optical axis in order to compensate for parallax. A fourth lens which is a fixed positive lens is closest to the eye-side.
