GB-GD-360-RB40 goniometer for 2π sources

Measurement of Radiant Intensity / Luminous Intensity

Irradiance/Illuminance detectors such us Gigahertz-Optik’s RW-37, UV-37, PD-9304, PD-9304 with PD-93RW can be used to measure radiant/luminous intensity of spot sources by converting measured irradiance by the inverse square law.

Measurement of Radiant Intensity / Luminous Intensity Distribution

Combined with the GB-GD-360-RB40 goniometer bench irradiance/illuminance detectors can also be used to measure the radiant/luminous intensity distribution of hemispherical emitting (2π) light sources.

Variable Measurement Distance

The GB-GD-360-RB40 goniometer is set-up with a up to three meter long rail benches (other sizes on request). Adjustment of the measurement distance between test source and detector from 100 mm to about 3 m is possible. This unique feature enables spatial distribution measurement of single LEDs as well as of larger size LED matrices or luminaires.

Remote Control Operation

Goniometer and light meter are remote PC controlled by Gigahertz-Optik’s S-XX software (e.g. S-BTS2048). The measurement sequence can be set in symmetrical or individual steps. Measurement data includes the spatial radiant intensity and data transfer into IES and EULUMDAT format. Also total radiant power or total luminous flux is calculated from the accumulated radiant/luminous intensity distribution data. Furhtermore 2D polar plots or 3D intensity distribution plots are available.
