    • A probe head for a coordinate measuring machine has a stylus resiliently suspended in a housing. A sensor arrangement serves for detecting deflections of the stylus relative to the housing. The sensor arrangement comprises at least one Hall sensor having a magnet and a Hall element arranged in a vicinity to each other. When the stylus is deflected, the magnet is laterally passed by the Hall element in a direction defined from the North Pole to the South Pole of the magnet or vice versa. A Hall voltage of changing polarity can be tapped at the Hall element then. A preferably linear range around the polarity change is processed in order to determine the deflection of the stylus.
    • 用于坐标测量机的探头具有弹性地悬挂在壳体中的触针。 传感器装置用于检测触笔相对于壳体的偏转。 传感器装置包括至少一个霍尔传感器,其具有磁铁和彼此附近布置的霍尔元件。 当触针偏转时,磁体在霍尔元件的横向方向上沿着从北极到磁极的南极方向限定,反之亦然。 然后可以在霍尔元件上敲击改变极性的霍尔电压。 处理极性变化周围的优选线性范围以确定触针的偏转。

    • The invention contemplates a method and apparatus for automatically performing digital measurement of vertex dioptric powers in the principal planes of toric spectacle lenses. A spectacle lens is transilluminated by a parallel-ray bundle of monochromatic light which, after passage through the spectacle lens, is limited by an annular stop in the immediate vicinity of the vertex of the spectacle lens. A beamsplitter divides the light which passes through the spectacle lens into two individual light beams. As a result, an elliptical figure is projected to two planes, in each of which is located at least one self-scanning diode line. Diode-line scanning develops intercepts of the projected elliptical figure, and from the positional locations of these intercepts (in relation to the local intercept of the optical axis) a computer performs a selected one of a plurality of evaluation procedures (a) to develop projected-figure reorientation or displacement as necessary to permit it then (b) to perform a desired measurement evaluation. Provision is made for automatic detection of whether a given spectacle lens is or is not within the currently set range of measurement capability and, if determined to be outside such range, the fact of such detection is operative to change optical elements of the apparatus for optimum measurement-range accommodation of the particular spectacle lens.
    • 本发明考虑了一种用于在复曲面眼镜的主平面中自动执行顶点屈光度数字测量的方法和装置。 眼镜镜片通过平行射线的单色光束照射,在穿过眼镜镜片之后,眼镜镜片被靠近眼镜镜片顶点的环形止挡限制。 分束器将通过眼镜镜片的光分成两个单独的光束。 结果,将椭圆形图形投影到两个平面,每个平面位于至少一个自扫描二极管线。 二维线扫描产生投影椭圆图的截距,并且从这些截距的位置位置(相对于光轴的局部截距),计算机执行多个评估过程(a)中选择的一个来开发投影的 - 根据需要配置重新定位或位移,以便(b)执行所需的测量评估。 规定了自动检测给定的眼镜镜片是否在当前设定的测量能力范围内,并且如果被确定为在该范围之外,则这种检测的事实可用于改变装置的光学元件以达到最佳 特定眼镜片的测量范围调节。
