The Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) is a meridian reflecting Schmidt telescope. Its optics comprise two roughly rectangular mirrors, each made up of a number of 1.1-metre hexagonal deformable segments, providing a focal plane 1.75 metres in diameter corresponding to a five-degree field of view. This focal plane is tiled with fibre-positioning units, attached to 4000 fibres which transfer light to sixteen spectrographs below. The larger spherical mirror MB (37 segments, fitting in a 6.67m x 6.09m rectangle) is located at an angle in a large slanted tunnel attached to a tower; the smaller corrector mirror MA (24 segments, fitting in a 5.72m x 4.4m rectangle) is in a dome at ground level.. Looking at the image opposite, MB is at the top of the left-hand supporting column of the tower, MA is in the left of the two domes at the right of the image (the rightmost, grey dome is an unrelated telescope), and the spectrographs are inside the right-hand column of the tower.
