LSG-1890BCCD/LSG-1800ACCD goniospectroradiometer is a high precision automatic goniophotometric instrument for luminous intensity distribution measurement with facility for rotating the light source. The LSG-1890BCCD/LSG-1800ACCD can do the spatial CCT test and the light intensity distribution test. It is for industrial laboratory photometric data measurement of luminaires such as LED luminaires, LED Plant Lighting, HID luminaires, fluorescent lamps and so on.
