Optical table setup

On the left is the cubic vacuum chamber which opens into the clean environment inside the FFU with the transparent PVC skirt. On top of the chamber are the electric feedthrough’s and the dual powermeter.  On the right is the dark chamber, an optical enclosure where the integrating sphere is placed. This enclosure is light tight, allowing inside to have any kind of optical elements. On top of it is the small power supply for the LED-Ring and the oscilloscope.

The optical table made of granite from Brütsch-Rüegger with size is 1500mm x 1000mm has a big hole for the vacuum pump connection underneath and stands on vibration isolator feet’s.
