Precision Angle Measuring Metal Multi Faceted Prism
Precision Angle Measuring Metal Multi Faceted Prism
Product Description
The metal multi-faceted prism is a high-precision standard instrument primarily used to verify the indexing error of optical indexing heads, indexing tables, goniometers, and other circular indexing instruments. It also serves as an angle positioning reference in high-precision machining or measurement applications.
This instrument is available in two variants: even and odd planes. The even-plane version features integer degree working angles and is used to verify large periodic errors in the shafting system of circular indexing instruments, as well as for diameter measurement. The odd-plane version features non-integer degree working angles, enabling comprehensive verification of both large periodic errors in the shafting system and small periodic errors of the micrometer, allowing for accurate determination of circular indexing instrument uncertainty.
