Opsira now offers more than 20 different types of goniometers based on two fundamental models gonio'2pi and gonio'4pi for the measurement of light sources, luminaires and scattered light distribution.
All Opsira goniometers are directly driven with absolute encoders enabling a very high measurement precision without the need of a reference run. The scope of the goniometers can be extended using cameras for colour measurement and by spectroradiometers, and additional detectors, to determine the angle dependent colour behaviour of light sources, luminaires or components.
Later upgrades of measurement applications are possible due to the modular system design. External control of the goniometer is also possible through an internet protocol interface.
