Disclosed herein are a protein chip substrate and a method for manufacturing the protein chip substrate. The system includes an adjustable x-ray source, such that characteristics of an x-ray probe beam output by the x-ray source can be adjusted to improve the resolution of the measurement system. On either side of the center of the tire building drum a driving nut is arranged on the spindle. A scan driving voltage is applied to the first scan driving chip and a scan driving voltage of the same level is applied to the second and third scan driving chips. The two lenses could be moved together with a single mechanical structure, or separately with two different manual controls.
