The NSI-OP-5904 Z-Plane Sensor is used along with the Z-Plane Laser to measure the planarity of a planar near-field scanner.  The NSI-OP-5904 sensor is mounted to a 45-degree angle bracket on the probe antenna platform. The sensor is illuminated by the rotating Z-plane laser beam. As the beam rotates, the sensor detects and processes probe Z-plane error and provides that information to the computer for analysis. The sensor has a measurement range of ±0.1-inch with 0.001-inch rms accuracy. Power on and beam detection LEDs provide visual indications of status. When combined with the NSI 2000 software, the sensor provides an automated technique to acquire an XY measurement grid of Z-error data. Using the Z-sensor and Z-laser, the grid can be easily updated to monitor scanner deformation over time. The Z-error grid may be used with NSI's on-the-fly error correction capability (requires probe Z-stage) to correct the probe position during antenna measurements.
