HPG1900 Goniophotometer (Double Arm version )

According to the requirements of CIE, IESNA and national standards, we have achieved testing methods as B-(B、A-a and C-y through rotating lamps. It is used to test the spatial light intensity distribution as well as variety luminosity parameter of indoor spotlight, cast light lamp and street light. It can work either with double arm or single arm.
