first class prize of science & technology progress award of CAS in 1989，second class prize of national science & technology progress award in 1991
It is first infrared telescope with aperture of larger than 1M researched and manufactured by China，which adopt R-C optical system with primary mirror aperture of 1.26M and with focal ratio of 1/30。Structural design of reducing weight was applied to the telescope and very thin mirror adopted firstly。For this reason its aperture ratio of performance--cost is very high。A chopping secondary mirror enables the telescope to detect very faint infrared celestial objects out of the much brighter sky background。
