Instrument Systems has released upgrades for its LGS 1000 goniometer, which is ideal for measuring angle-dependent spatial radiation characteristics of large LED modules, solid-state lighting (SSL) products, as well as lamps and luminaires.
The LGS 1000 can be operated together with a photometer as a conventional goniophotometer or with a spectrometer as a high-quality goniospectroradiometer. This allows important performance characteristics such as luminous intensity distribution curves, luminous flux, colour coordinates and even colour rendering index to be measured.
As an optional accessory, the newly developed luminous flux integrator allows the characteristics of lamps and luminaires to be determined in their required burning position. An added benefit is that the measurements can be taken faster and are more accurate. Furthermore, Instrument Systems supplies an innovative correction procedure for position-sensitive samples.
Alongside the new accessory options, the basic version of the goniometer also offers an array of advantages. Accessible steps allow samples up to 2m in diameter and weighing 50kg to be mounted easily. The two synchronously controlled servo motors with precision angle encoders facilitate simultaneous movement with minimal vibration. The reproducibility of the sample positioning is smaller than 0.1° at nominal load. The SpecWin Pro software package offers easy evaluation and reporting of the measured data.
