  • LSG-1800CCD/LSG-1700CCD goniospectroradiometer is an automatic goniophotometric instrument for luminous intensity distribution measurement with facility for rotating the light source. The LSG-1800CCD can do the spatial CCT test and the intensity distribution test. It is for industrial laboratory photometric data measurement of luminaires such as LED luminaires, HID luminaires, fluorescent lamps and so on.

    LSG 1800CCD Goniospectroradiometer Darkroom

    • Meets the requirements of CIE, IEC, IES LM-79 & GB standards
