Measurement of the GR reflection for AA telescope(after the installation of the first lens)

Aritomi and Yuhang

To make sure everything is going well, we decided to perform this measurement. From the simulation, beam waist should be 53.5cm after the lens and has size 146um.

From the measurement, the beam waist is 59cm after the lens and has a size around 80um. This is out of our exception.

Shall we adjust the telescope according to this measurement?
