Check and flatten the wavefront in laser room
This procedure assumes that the wavefront sensor (WFS) and focus imaging are already setup, and no significant modification was added to the configuration.
Currently the WFS beampath is picked off after the first turning mirror after the DM. A f=1m lens (~f/20) combined with a f=100mm lens images the surface of the DM on the sensor.
The focus of the 1m lens is picked off by a flipping mirror and imaged by a 10X objective coupled to a CCD camera.
