In 1981, HS88/23 and HS152/23
aerial surveysurvey cameras,
which were both key national
scientific research projects,
were successfully developed.
This marks a new research level
in largediameter lens and
multi-layer coating technology.
This filled domestic technology
void in the area and won Jiangsu
Province Science Award, as well
as Second Place in the 1985 and 1986 Ministry of Machine Scientific
