Goniophotometer

A goniophotometer is a precision instrument used to measure the light distribution and intensity emitted or reflected by a lighting device, such as lamps, LEDs, or luminaires. It rotates the light source and sensors to capture how light spreads in different directions, providing detailed data on its beam pattern. This information helps manufacturers and engineers assess the performance of lighting products, ensure they meet regulatory standards, and optimize designs for better light efficiency and safety. Essentially, it’s a specialized tool for analyzing the shape and reach of light from a source.
