Product description

Are two surfaces really parallel or perpendicular to each other? Is the machining axis perpendicular to the machined surface (reference plane) or are two surfaces of a casing parallel?

PENTALIGN is a high precision rotating pentaprism. In conjunction with an external laser source, it generates a laser plane precisely perpendicular to the incident laser beam. With the two-axis adjustment sensor in the prism, the plane spanned by the laser can be measured with an accuracy of 0.01 mm after reflection. PENTALIGN can be used to determine the parallelism of the surfaces of tower segments in wind turbines, gear shafts, housings, surfaces of presses, or ship propellers.
