N2 - We present a simple and low-cost optical measurement system to measure simultaneously five-degrees-of-freedom error motions of high-speed microspindles. In this study, measurement error due to displacement of an irradiation laser spot on a 3 mm diameter ball lens is analyzed. The results show that the maximum error in the Z direction due to the 7μm displacement of the laser spot in the X direction is about 0.15 nm, i.e., the change of the laser beam irradiation point of the ball lens caused by the radial displacement has little effect on the measurement accuracy.
