    NSI-OP-5928
 XY Optical Measurement Subsystem

DESCRIPTION

The NSI-OP-5928 XY Optical Measurement Subsystem is intended for use on vertical (figure above) or horizontal (figure below) planar near-field scanners to measure up to six parameters of distance and deformation of the probe line of travel. Two distance parameters include optical interferometer measurements of the X and Y travel. Four deformation parameters include the Yerr and Zyerr error as the probe moves in the X direction, and the Xerr and Zxerr error as the probe moves in the Y direction of travel. The NSI-OP-5928 XY Optical Measurement Subsystem includes the NSI-OP-5906A XY Optics Assembly, XY Laser, X and Y retroreflectors, laser alignment mirrors, DSP interface unit, software, cables, mounting brackets, installation and alignment on your scanner.
