General Description
We can extract optical beams at the viewports from the interferometer inside the vacuum chamber. The optical beams are for length control scheme of the interferometer, alignment control scheme of the mirrors, optical levers for LCGT-SUS, and other monitoring devices (CCD or equivalent video cameras).
Stray lights?
- AR coating for 1064 nm and 532 nm
- Wedge angle
