All ACCU-Place Macro Calibration Standards have both X & Y axis metric scales. These dual axis standards are ideal for calibrating optical magnification, linear distance, stage motion as well as squareness of stage. In addition, with the larger area calibration scale, the calibration of low power optical systems over the longer distances can be easily carried out.
