More than twenty specialists from various field including astronomy,astronomical instrument,optics,precision mechanics,electronocs and management science gave overall and synthetical evaluation for small lamost.

  On June 18 and 28 2007,Specialist group was sent to Xingrong station of National observatory for testing and inspecting on site.

  After listening report of research and development from project headquarters for lamost and testing report of small lamost from testing specialist group meanwhile inspecting relevant technical information ,specialists reach accordant opinion as follows:

  'The optical quality of Small LAMOST has been satisfied very well with the target specifications.Firstly, 80% of star energy is encircled within a diameter of 2 arc sec and high image quality was obtained among 3-degree field of view(FOV).

  Secondly, the goal of multi-object fiber spectroscopic system has been achieved and works normally.

  Thirdly, the whole observation system has been well integrated with telescope, fibers, spectrograph and CCD cameras.

  The mission of Small LAMOST has been completed. The success of Small LAMOST's development proves that the project entire proposal is correct, its technology and technics are feasible.'

  Small lamost is composed of mirror with aperture of 3 meter(effective aperture of 2 meter)，250 fibres，one spectrograph，two 4kx4k ccd camera，overall alt-azimuth mounting，tracking and controlling system.
