Auxiliary Optics Lists
This is a preliminary list of auxiliary optics, sensors and other stuff.
ITM
- Optical lever
- Local sensors to monitor the position of the test mass
- At least horizontal degrees of freedom (X,Y)
- Preferably a vertical sensor (Z)
- The sensors have to be rigidly mounted on the ground so that these are useful for remembering the position of the mirror and recording the drifts.
- Suspended baffles (suggested by Riccardo)
- Suspended beam dumps for AR reflected beams.
- CCD camera to look at the mirror surface.
ETM
- Suspended beam reducing telescope for transmitted beam.
- Vibration isolation requirement TBD
- Detection optics for transmitted beam, especially QPD (suspended ? in vacuum ?)
- Optical lever
- Local sensors to monitor the position of the test mass
- At least horizontal degrees of freedom (X,Y)
- Preferably a vertical sensor (Z)
- The sensors have to be rigidly mounted on the ground so that these are useful for remembering the position of the mirror and recording the drifts.
- Suspended baffles to kill scattered light (suggested by Riccardo)
- Suspended beam dumps for killing AR reflected beams.
- CCD camera to look at the mirror surface.
BS
- Suspended steering mirrors to lead the POX/POY beams out of the vacuum chamber.
- Detection optics for POX/POY.
- Optical Lever
- Local sensors to monitor the position of the mirror
