此装置是用精密多齿盘与光电测微平行光管构成的一种精密测角装置。由于精密多齿盘具有分度精度高、使用寿命长及操作方便等特点,而光电测微平行光管能自动瞄准,因此构成的测角装置能广泛用于精密角度计量。精度可达到0.4″,是国内少有的一种测角方法和装置。经两年多的测试卖践表明该装置用于各种透明和非透明光学棱镜、光学多面体(四面体、八面体、二十四面体等),光学平板等角度与平行差的测试,都能得到满意的结果。
This device is a precision multi-gear plate and optical micrometer parallel light pipe consisting of a precision angle measuring device. Precision multi-gear with indexing accuracy, long life and easy operation and other features, and optical micrometer parallel light pipe can automatically aim, so the composition of the angle measuring device can be widely used in precision angle measurement. Accuracy of up to 0.4 ", is a rare method and device for measuring angle.After more than two years of testing practice shows that the device is used for a variety of transparent and non-transparent optical prism, optical polyhedron (tetrahedron, octahedron, Twenty-four tetrahedron, etc.), optical flat angle and the difference between the parallel test, can get satisfactory results.
