Goniophotometer RiGO801 - 300

Type C goniophotometer for LEDs/OLEDs, lamps and small luminaires of a diameter up to 300 mm
Goniophotometer RiGO801 - 300

This free-standing type C goniophotometer has a maximum measuring volume of a diameter of 300 mm, and is well suited for measurement objects ranging from LEDs/OLEDs and lamps up to small luminaires. The measuring camera and the other sensors being mounted on two axes linked with each other are moved on a spherical surface around the stationary object to be measured.

The goniometer is mounted in an external frame in an entirely pivotable manner so that vertical just as horizontal burning positions can be set. This is particularly important for measuring automotive lamps as a stable horizontal burning position is urgently necessary here.

The high position accuracy of the ray data measured allows the ray data measurement of light sources from the size of a power LED on (chip surface area from approx. 1x1 mm² on). The luminous intensity distribution and the luminous flux of much smaller light sources can still be measured as the measurement will then be carried out by the photometer in the far-field mode. With the option goniospectroradiometer spectral and colorimetric data can be measured according to LM79 and EN13032-4.
