Precision Angle Measuring Metal Multi Faceted Prism
Product Description
Metal multi-faceted prism is a high-precision standard instrument, which is mainly used to verify the indexing error of optical indexing head, indexing table, goniometer and other circular indexing instruments, and can also be used as an angle positioning reference in high-precision machining or measurement.
It is divided into two kinds of even and odd planes, the working angle of the former is the integer degree, it is used to verify the large periodic error of the shafting system of the circular indexing instrument, and can also be used for diameter measurement; And the working angle of the latter is a non-integer degree, which can comprehensively verify the large period of the shafting system of the circular indexing instrument and the small period error of the micrometer, and can correctly determine the uncertainty of the circular indexing instrument.
