Product Description

6150 Graduated Glass Target

1½” dia. Glass Target in Steel Ring Mount

The 6150multiple paired-line glass target, with horizontal and vertical displacement scales, is mounted in a hardened and ground stabilized steel ring. It is centered within 0.0005″ with respect to the outside diameter of the ring. This target is useful when you need to measure or estimate deviations from a line of sight which exceed an optical micrometer’s range. The graduations on the target act as “scale” and may be read using the optical micrometer as a vernier in much the same way that optical tooling scales are read. 
National Stock Number: NSN-6920-00-X11-1495.
The displacement scales on the glass are graduated up to 0.300″ on each side of zero (left). The large divisions read 0.050″, and the smaller ones, 0.010″.
