A probe control interface is provided for a structured light non-contact coordinate measuring machine probe. The pivot mechanism includes a pedestal having a bore passing through the pedestal; a shaft inserted into the bore and having at least two leaning surfaces in parallel to an extending direction of the shaft; two bushes coupled to the shaft and fixed in the bore; and a reed set disposed in the bore and arranged between the two bushes. A air spring assembly may include a first air spring mount mounted to move with the rod, a second air spring mount on the second support element, and a tubular air spring mounted on the first and second air spring mounts and defining a air spring interior to hold a quantity of air. The length of the telescoping section may be locked by rotating the inner tube with respect to the outer tube. This composition is obtained by passing a resist composition, which is obtained by dissolving a resin component that displays changed alkali solubility under the action of acid and an acid generator component that generates acid upon exposure in an organic solvent, through a filter equipped with a polyethylene hollow thread membrane. This device may be cleaned and sterilized for reuse.
