LEDGON - Goniophotometer

The LEDGON goniophotometer from Instrument Systems determines the spatial radiation pattern of LEDs and small LED modules. Measurement is made over the whole forward hemisphere of an emitting LED. A high angle resolution of 0.1° means exact measurements even for narrow emission angle LEDs. In combination with the CAS 140CT spectroradiometer, additional spectral parameters, such as the angle dependence of color coordinates or color temperature, can also be measured. White LEDs, for example, exhibit a significant angle dependence of the color temperature.
