Guo Shoujing Telescope

The Guo Shoujing Telescope is a Chinese created large field of view and large aperture spectroscopic survey telescope, abbreviated as LAMOST. Internationally, it was the first to develop a large-scale spectral survey that simultaneously observes the spectra of thousands of celestial bodies, capable of observing 4000 celestial bodies at the same time, greatly promoting the study of the formation and evolution of the Milky Way and general galaxies.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

LAMOST is the English abbreviation for "Large Area Multi Object Fiber Optic Spectral Astronomical Telescope". It is a spectral survey telescope that uses spectroscopic methods to study the physical properties and chemical composition of celestial bodies. LAMOST consists of three parts: a reflective Schmidt correction mirror, a spherical main mirror, and a focal plane. Among them, the reflective Schmidt correction mirror is a mirror composed of 24 hexagonal plane sub mirrors spliced together, which can reflect the light emitted by celestial bodies onto the spherical main mirror. The spherical main mirror is a reflection mirror with a diameter of 6.5 meters, which can focus light onto the focal plane. 4000 optical fibers are installed on the focal plane, which can guide light to the spectrometer.
