During rough adjustment: the laser optical axis is considered as the normal axis of measurement optical path, and the coaxal measurement system is established. During careful adjustment: the tilt coefficient of WYGO interferometer is considered as the adjustment standard to adjust the objective, so the actual result of the object surface quality is ensured.
