A single of the most important “secret rituals” of an astronomical observatory is the aluminising of the telescope’s mirror. The four-metre most important mirror of the Anglo-Australian Telescope (AAT) is a enormous chunk of finely polished glass-ceramic that has been coated with a skinny layer of aluminium to create the reflective surface.
About time, the surface of the mirror collects dust and dust from the air, and from birds and bats traveling, at times leaving a dropping or two!
So the moment a year, the professionals at the Australian Astronomical Observatory (AAO) eliminate the 16 tonne mirror from the telescope’s guidance framework and put together the mirror for aluminising. First, they strip off the outdated reflective coating, then put together and polish the glass surface, and lastly safe the mirror inside the huge vacuum chamber metal tank for aluminising.
The easy glass surface is covered with a few grams of aluminium, distribute out in a layer only a hundred atoms thick.
