LEDGON 100

The LEDGON goniophotometer from Instrument Systems determines the angle-dependent spatial radiation properties of LEDs and small LED modules. The entire hemisphere in the direction of radiation of the LED can be measured. Thanks to the high angle resolution of 0.1° exact readings can be obtained for narrow-angled LEDs.

In combination with the CAS 140D spectroradiometer, spectral parameters, e.g. angle-dependent color coordinates or color temperature, can also be measured. This is particularly important for white LEDs, as the color temperature can vary considerably, depending on the beam angle.
