2.Goniophotometer for LEDs

Designed for measuring the luminous intensity distribution curve, luminous intensity, luminous flux, spread angel of light beam, In- IF, IF-VF, and electrical characteristics of LEDs.
For low power LEDs, we have the LED 626 Goniophotometer to meet the requirement of CIE 127 condition A and condition B.
For high power LEDs, a much longer measurement distance is required, the GO-SPEX100 or GO-I300 is recommended.
Equipped with a spectroradiometer, the system can measure the spatial color distribution and the non-uniformity.
