Instrument Systems Presents a Goniophotometer System for Angular-Resolved Measurements on a Large Scale

The LGS 1000 from Instrument Systems allows angledependent spatial radiation characteristics of large LED modules, solid-state lighting (SSL) products, as well as lamps and luminaires to be determined. The Munich-based company is presenting key upgrades for its largest goniometer system at this year's Light+Building fair in Frankfurt.

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 all important performance characteristics such as luminous intensity distribution curves, luminous flux, color coordinates and even color 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. If a low-maintenance measuring system with a compact footprint is a top priority, the LGS 1000 together with correction of the burning position provides a genuine alternative to a large and expensive rotating mirror goniophotometer.

Alongside the new accessory options, the basic version of the goniometer also offers an array of advantages. Accessible steps allow samples up to 2 m in diameter and weighing 50 kg to be easily mounted. Notwithstanding the robust dimensions, the LGS 1000 can still be accommodated in a laboratory with a standard ceiling height. 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 comprehensive SpecWin Pro software package offers easy evaluation and reporting of the measured data. Alongside a turnkey solution for electrical drive and measurement of samples, SpecWin Pro can generate the important IES and EULUMDAT formats for the lighting industry.
