On April 15 2005，specialists organised by scientific division carried on reviewing  for prototype of low resolution spectrograph of LAMOST。Specialists group respectively listened to specification requirement on low resolution spectrograph provided by scientific division and research report as well as test report provided by engineering division meanwhile inspecting the locale。It was concluded that main specification of spectrograph such as spectra resolution etc had met requirement of design and match optical computation within spectra coverage range of CCD。Some performance specification can not be tested because of the limitation of experimental condition。
