1. Basic working principle

GO-R5000 is based on CIE C-γ system and measures intensity distribution on C-planes or cone surfaces. It can also achieve CIE A-α,CIE B-β solutions by software. GO-R5000 can be widely used in the measurement of all types of lighting sources like  lamps, luminaires, indoor lights, outdoor lights, street lights, flood lights with very high accuracy.

Export format: *.GOS *.CIE *.CEN *.IES *.TM14 *.CIB *.LDT, which can directly match International Universal Lighting Design Software, such as Dialux, AGI32, Lumen-Micro.

The spatial spectral/colorimetric quantities and spectral/color uniformity (optional) and luminance distribution and luminance uniformity (optional) can be achieved by the goniophotometer system.
