The Optical Layout of GEO600
The greenish regions inside the tanks close to the walls are support platforms for the vibration isolation stacks. They restrict the area where the optical components can be placed.
The large brown boxes with blue borders represent the optical tables.
Optical components are coloured in a light blue with black borders exept of those which (partially) reflect light, which are drawn in a darker shade of blue.
The thickness of the beams is drawn according to their real diameter, whereas the colour of the beams indicate the intensity: the stronger the red of the beam the higher the intensity.
This is version 1.48 of the GEO600 optical layout, generated by means of OptoCad_0.83c. Final positions for the tanks TCOa and TCOb. Beam telescope for modematching to output optics inside TCOa/TCOb. With additional tank TCOc on the detection bench. BS thermal lens assumed to have f = 11 km. Represents the situation at April 2006.
