Lifting and moving the spectrometer arm also affects the position of the sample in the manipulator as they share the same support stone. It is crucial that the sample is returned to its position after changing the angle of the spectrometer arm. At 7 min 45 s the spectrometer arm is lifted on its air feet, at 8 min 47 s it is moved 10 cm forward and at 9 min 18 s it is moved the same distance back. At 10 min 20 s the arm was lowered and air flow turned off. In the measurement, the difference in position before and after motion is 180 nm. |
