One of the most important “secret rituals” of an astronomical observatory is the aluminising of the telescope’s mirror. The 4-metre primary mirror of the Anglo-Australian Telescope (AAT) is a huge chunk of finely polished glass-ceramic that has been coated with a thin layer of aluminium to create the reflective surface.
Over time, the surface of the mirror collects dust and dirt from the air, and from birds and bats flying, occasionally leaving a dropping or two!
So once a year, the technicians at the Australian Astronomical Observatory (AAO) remove the 16 tonne mirror from the telescope’s support structure and prepare the mirror for aluminising. First, they strip off the old reflective coating, then prepare and polish the glass surface, and finally secure the mirror inside the large vacuum chamber metal tank for aluminising.
The smooth glass surface is covered with a few grams of aluminium, spread out in a layer only 100 atoms thick.
